Rev.2.4_00 HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION S-1701 Series The S-1701 Series, developed based on CMOS technology, is a voltage regulator with a reset function and integrates a highaccuracy voltage detector with on-chip delay circuit and a positive voltage regulator with a low dropout voltage and high output voltage on one chip. The S-1701 Series is available in many types according to the selection of the voltage detector block of the voltage detector, including a SENSE pin input product. A built-in low on-resistance transistor provides a low dropout voltage and large output current. Small ceramic capacitors are available and an external capacitor for delay is needless. Small SOT-23-5 and SOT-89-5 packages realize high-density mounting.

Seiko Instruments Inc. 33 HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION Rev.2.4_00 S-1701 Series Selection of Input and Output Capacitors (CIN, CL) The S-1701 Series requires an output capacitor between the VOUT and VSS pins for phase compensation. A ceramic capacitor with a capacitance of 1.0 F or more provides a stable operation in all temperature ranges. When using an OS capacitor, tantalum capacitor, or aluminum electrolytic capacitor, a capacitor with a capacitance of 1.0 F or more and an ESR of 10 or less is required. The output overshoot and undershoot values, which are transient response characteristics, vary depending on the output capacitor value. The required capacitance value for the input capacitor differs depending on the application. The recommended application values are CIN = 1.0 F or more and CL = 1.0 F or more, however, perform thorough evaluation using the actual device, including evaluation of temperature characteristics. Explanation of Terms Regulator block 1. Low dropout voltage regulator The low dropout voltage regulator is a voltage regulator whose dropout voltage is low due to its built-in low on-resistance transistor. 2. Low ESR A capacitor whose ESR (Equivalent Series Resistance) is low. The S-1701 Series enables use of a low ESR capacitor, such as a ceramic capacitor, for the output-side capacitor (CL). A capacitor whose ESR is 10 or less can be used. 3. Output voltage (VOUT) The accuracy of the output voltage is ensured at 1.0% under the specified conditions of fixed input voltage*1, fixed output current, and fixed temperature. *1. Differs depending on the product. Caution If the above conditions change, the output voltage value may vary and exceed the accuracy range of the output voltage. Please see the electrical characteristics and attached characteristics data for details. VOUT 1 4. Line regulation VIN * VOUT Indicates the dependency of the output voltage on the input voltage.

Load regulation (VOUT2) Indicates the dependency of the output voltage on the output current. That is, the values show how much the output voltage changes due to a change in the output current with the input voltage remaining unchanged. 6. Dropout voltage (Vdrop) Indicates the difference between the input voltage VIN1, which is the input voltage (VIN) at the point where the output voltage has fallen to 98% of the output voltage value VOUT3 after VIN was gradually decreased from VIN = VOUT(S) + 1.0 V, and the output voltage at that point (VOUT3 x 0.98).

Detection voltage (-VDET), Release voltage (+VDET) The detection voltage (-VDET) is the voltage at which the output switches to low. The detection voltage varies slightly among products of the same specification. The variation of detection voltage between the specified minimum (-VDET) Min. and the maximum (-VDET) Max. is called the detection voltage range (refer to Figure 29). e.g. For a product with -VDET = 3.0 V, the detection voltage is a value in the range of 2.97 V (-VDET) 3.03 V. This means that some products have 2.97 V for -VDET and some have 3.03 V. The release voltage (+VDET) is the voltage at which the output switches to high. The release voltage varies slightly among products of the same specification. The variation of release voltages between the specified minimum (+VDET) Min. and the maximum (+VDET) Max. is called the release voltage range (refer to Figure 30). e.g. For a product with -VDET = 3.0 V, the release voltage is a value in the range of 3.059 V (+VDET) 3.242 V. This means that some products have 3.059 V for +VDET and some have 3.242 V. VIN (-VDET) Max. (-VDET) Min. VIN Detection voltage Detection voltage range Release voltage (+VDET) Max. (+VDET) Min.

Hysteresis width (VHYS) The hysteresis width is the voltage difference between the detection voltage and the release voltage. The existence of the hysteresis width prevents malfunction caused by noise on the input voltage. 3. Delay time (tD) The delay time is a time internally measured from the instant at which the voltage input to the VDD pin exceeds the release voltage (+VDET) to the point at which the output of the OUT pin inverts.

Through-type current The through-type current refers to the current that flows instantaneously when the voltage detector detects and releases a voltage. The through-type current flows at a frequency of 20 kHz during the release delay time since the internal logic circuit operates. Seiko Instruments Inc. 37 HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION Rev.2.4_00 S-1701 Series 5. Oscillation In applications where a resistor is connected to the input side (Figure 32), the through-type current which is generated when the output goes from low to high (release) causes a voltage drop equal to [through-type current] x [input resistance] across the resistor. When the input voltage drops below the detection voltage as a result, the output voltage goes from high to low. In this state, the throughtype current stops, its resultant voltage drop disappears, and the output goes from low to high. The through-type current is then generated again, a voltage drop appears, and repeating the process finally induces oscillation.

Be sure that VOUT does not exceed VIN + 0.3 V to prevent the voltage regulator from being damaged due to inverse current flowing from the VOUT pin through a parasitic diode to the VIN pin. 40 Seiko Instruments Inc. HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION Rev.2.4_00 S-1701 Series 3. Shutdown pin (ON/OFF pin) (S-1701 Series A/ B/ C/ D/ E/ F/ G/ H/ J/ K/ L/ M types) This pin starts and stops the regulator. When the ON/OFF pin is set to the shutdown level, the operation of all internal circuits stop, and the builtin P-channel MOS FET output transistor between the VIN pin and VOUT pin is turned off to substantially reduce the current consumption. At this time, the current consumption equals that consumed by the detector block, because the internal circuits of the detector are operating. The VOUT pin becomes the VSS level due to the internally divided resistance of several hundred k between the VOUT pin and VSS pin. The structure of the ON/OFF pin is as shown in Figure 35. Since the ON/OFF pin is neither pulled down nor pulled up internally, do not use it in the floating state. In addition, note that the current consumption increases if a voltage of 0.3 V to VIN - 0.3 V is applied to the ON/OFF pin. When the ON/OFF pin is not used, connect it as follows according to the product type. * S-1701 Series A/ B/ C/ D/ E/ F types: Connect to the VIN pin. * S-1701 Series G/ H/ J/ K/ L/ M types: Connect to the VSS pin.

Parasitic diode Figure 36 Block Diagram (Detector Block) (1) When the SENSE voltage (VSENSE) is higher than the release voltage (+VDET), the Nch transistor is OFF and VIN (high) is output. Since the Nch transistor N1 in Figure 36 is OFF, (Rb + Rc) * VSENSE the comparator input voltage is . Ra + Rb + Rc (2) When VSENSE goes below +VDET, VIN is output, as long as VSENSE remains above the detection voltage (-VDET). When the VSENSE falls below -VDET, the Nch transistor becomes ON and VSS is output. At this time, the Nch transistor N1 in Figure 36 Rb * VSENSE . becomes ON, and the comparator input voltage is changed to Ra + Rb (3) When VIN falls below the minimum operating voltage, the output becomes undefined. In this case the output becomes VIN because it is pulled up. (4) VSS is output when VIN rises above the minimum operating voltage. The VSS level still appears even when VSENSE surpasses -VDET, as long as it does not exceed the release voltage +VDET. When VSENSE rises above +VDET, the Nch transistor becomes OFF and VIN is output. VIN at the VDOUT pin is delayed for tD due to the delay circuit.

Figure 37 Operation 2. Delay circuit The delay circuit delays the output signal from the time when the SENSE voltage (VSENSE) exceeds the release voltage (+VDET) when VSENSE is turned on (refer to point B in Figure 37). The output signal is not delayed when VSENSE goes below the detection voltage (-VDET) (refer to point A in Figure 37). The delay time (tD) is a fixed value that is determined by a built-in clock generator which consists of constant current an a capacitor, and counter. 3. Delay circuit output voltage detection type (S-1701 Series D/ E/ F/ K/ L/ M/ U/ V/ W types) If the input voltage or load current changes transiently, an undershoot or overshoot occurs in the output voltage of the regulator. In the product types in which the output voltage of the regulator is detected by the detector, if the output voltage is the detection voltage or lower due to the undershoot, the detector operates and a reset signal may be output. To prevent this, set the value of the inputand-output capacitor of a regulator so that the undershoot is the minimum value or set a voltage range that allows the difference between the output voltage and detection voltage to be equal to or greater than the undershoot. Seiko Instruments Inc. 43 HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION Rev.2.4_00 S-1701 Series Explanation for Each Type 1. S-1701 Series A/ B/ C types The S-1701 Series A/ B/ C types provide a regulator block standby mode realized by an ON/OFF function that is active high. The internal circuit of the detector operates in the standby mode, so only the current that the detector consumes flows. The SENSE pin is connected to the VIN pin in the internal circuit of the detector block, so the voltage applied to the VIN pin is monitored and a reset signal is output from the VDOUT pin. The built-in counter timer allows selection of the release delay time from three settings (A: No delay (60 s), B: 50 ms, C: 100 ms). The power supply is shared by the regulator block and detector block and supplied from the VIN pin, so care must be taken concerning VIN pin input impedance*1. 2. S-1701 Series D/ E/ F types The S-1701 Series D/ E/ F types provide a regulator block standby mode realized by an ON/OFF function that is active high. The internal circuit of the detector operates in the standby mode, so only the current that the detector consumes flows. The SENSE pin is connected to the VOUT pin, which is an output of the regulator, in the internal circuit of the detector block, so the output voltage of the regulator (VOUT) is monitored and a reset signal is output from the VDOUT pin*2. The built-in counter timer allows selection of the release delay time from three settings (D: No delay (60 s), E: 50 ms, F: 100 ms). The power supply is shared by the regulator block and detector block and supplied from the VIN pin, so care must be taken concerning the VIN pin input impedance*1. 3. S-1701 Series G/ H/ J types The S-1701 Series G/ H/ J types provide a regulator block standby mode realized by an ON/OFF function that is active low. The internal circuit of the detector operates in the standby mode, so only the current that the detector consumes flows. The SENSE pin is connected to the VIN pin in the internal circuit of the detector block, so the voltage applied to the VIN pin is monitored and a reset signal is output from the VDOUT pin. The built-in counter timer allows selection of the release delay time from three settings (G: No delay (60 s), H: 50 ms, J: 100 ms). The power supply is shared by the regulator block and detector block and supplied from the VIN pin, so care must be taken concerning the VIN pin input impedance*1. 4. S-1701 Series K/ L/ M types The S-1701 Series K/ L/ M types provide a regulator block standby mode realized by an ON/OFF function that is active low. The internal circuit of the detector operates in the standby mode, so only the current that the detector consumes flows. The SENSE pin is connected to the VOUT pin, which is an output of the regulator in the internal circuit of the detector block, so the output voltage of the regulator (VOUT) is monitored and a reset signal is output from the VDOUT pin*2. The built-in counter timer allows selection of the release delay time from three settings (K: No delay (60 s), L: 50 ms, M: 100 ms). The power supply is shared by the regulator block and detector block and supplied from the VIN pin, so care must be taken concerning the VIN pin input impedance*1. 44 Seiko Instruments Inc. HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION Rev.2.4_00 S-1701 Series 5. S-1701 Series N/ P/ Q types The S-1701 Series N/ P/ Q types do not provide an ON/OFF function because the ON/OFF pin is connected to the VIN pin in the circuit. The detector block features the external SENSE pin, which allows monitoring of other power supplies. The SENSE pin is configured only by a resistor, so instantaneous current such as through-type current does not flow through this pin. This allows precise monitoring of the input power supply by connecting the SENSE pin to the input power supply even when a resistor (RIN) is connected between the input power supply and the VIN pin. The built-in counter timer allows selection of the release delay time from three settings (N: No delay (60 s), P: 50 ms, Q: 100 ms). The power supply is shared by the regulator block and detector block and supplied from the VIN pin, so care must be taken concerning the VIN pin input impedance*1. 6. S-1701 Series R/ S/ T types In the S-1701 Series R/ S/ T types, the VDOUT pin, which is the output pin of the detector, is connected to the ON/OFF pin of the regulator in the circuit. This allows setting of the regulator to the standby mode at the same time as the VDOUT pin outputs a RESET signal. The detector block features an external SENSE pin, which allows monitoring of other power supplies. The SENSE pin is configured only by a resistor, so instantaneous current such as through-type current does not flow through this pin. This allows precise monitoring of the input power supply by connecting the SENSE pin to the input power supply even when a resistor (RIN) is connected between the input power supply and the VIN pin. The built-in counter timer allows selection of the release delay time from three settings (R: No delay (60 s), S: 50 ms, T: 100 ms). The power supply is shared by the regulator block and detector block and supplied from the VIN pin, so care must be taken concerning the VIN pin input impedance*1. 7. S-1701 Series U/ V/ W types The S-1701 Series U/ V/ W types do not provide an ON/OFF function because the ON/OFF pin is connected to the VIN pin in the circuit. The SENSE pin is connected to the VOUT pin, which is an output pin of the regulator, in the internal circuit of the detector block, so the output voltage of the regulator (VOUT) is monitored and a reset signal is output from the VDOUT pin*2. The built-in counter timer allows selection of the release delay time from three settings (U: No delay (60 s), V: 50 ms, W: 100 ms). The power supply is shared by the regulator block and detector block and supplied from the VIN pin, so care must be taken concerning the VIN pin input impedance*1. 8. S-1701 Series X/ Y/ Z types The S-1701 Series X/ Y/ Z types do not provide an ON/OFF function because the ON/OFF pin is connected to the VIN pin in the circuit. The SENSE pin is connected to the VIN pin in the internal circuit of the detector block, so the voltage applied to the VIN pin is monitored and a reset signal is output from the VDOUT pin. The built-in counter timer allows selection of the release delay time from three settings (X: No delay (60 s), Y: 50 ms, Z: 100 ms). The power supply is shared by the regulator block and detector block and supplied from the VIN pin, so care must be taken concerning the VIN pin input impedance*1. Seiko Instruments Inc. 45 HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION Rev.2.4_00 S-1701 Series *1. In S-1701 series, when connecting the resistance RIN between an input power supply pin and a VIN pin, and defining the current which flows into RIN as IIN, VIN pin voltage falls by VIN = IINxRIN at the time of overload, and changes by VIN = IINxRIN at the time of load change. Thereby, keep in mind that phenomena, such as output voltage falls and an output oscillation, occur. *2. If the input voltage or load current changes transiently, an undershoot or overshoot occurs in the output voltage of the regulator. In the product types in which the output voltage of the regulator is detected by the detector, if the output voltage is the detection voltage or lower due to the undershoot, the detector operates and a reset signal may be output. To prevent this, set the value of the input-and-output capacitor of a regulator so that the undershoot is the minimum value or set a voltage range that allows the difference between the output voltage and detection voltage to be equal to or greater than the undershoot. 46 Seiko Instruments Inc. HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR WITH RESET FUNCTION Rev.2.4_00 S-1701 Series Precautions * Wiring patterns for the VIN, VOUT and GND pins should be designed so that the impedance is low. When mounting an output capacitor between the VOUT and VSS pins (CL) and a capacitor for stabilizing the input between the VIN and VSS pins (CIN), the distance from the capacitors to these pins should be as short as possible. * Note that the output voltage may increase when a series regulator is used at low load current (1.0 mA or less). * Generally, a series regulator may cause oscillation depending on the selection of external parts. The following conditions are recommended for this IC. However, be sure to perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperature characteristics. Input capacitor (CIN): 1.0 F or more 1.0 F or more Output capacitor (CL): Equivalent series resistance (ESR): 10 or less * The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitor is small or an input capacitor is not connected. * The application conditions for the input voltage, output voltage, and load current should not exceed the package power dissipation. * Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit. * In determining the output current, attention should be paid to the output current value specified in Tables 25 to 30 in the electrical characteristics and footnote *7 of the table. * SII claims no responsibility for any disputes arising out of or in connection with any infringement by products including this IC of patents owned by a third party.
