Figure 14 Caution The above connection diagram and constant will not guarantee successful operation. Perform thorough evaluation using the actual application to set the constant. Condition of Application Input capacitor (CIN) : 1.0 F or more 1.0 F or more (Ceramic capacitor) Output capacitor (CL) : Capacitor for soft-start (CSS) : 0.22 nF to 22 nF (Ceramic capacitor) Caution A general series regulator may oscillate, depending on the external components. Confirm that no oscillation occurs in the application for which the above capacitors are used. Selection of Input and Output Capacitors (CIN, CL) The S-1137 Series requires an output capacitor between the VOUT and VSS pin for phase compensation. Operation is stabilized by a ceramic capacitor with an output capacitance of 1.0 F or more over the entire temperature range. When using an OS capacitor, tantalum capacitor, or aluminum electrolytic capacitor, the capacitance must be 1.0 F or more. The value of the output overshoot or undershoot transient response varies depending on the value of the output capacitor. The required capacitance of the input capacitor differs depending on the application. The recommended capacitance for an application is CIN 1.0 F, CL 1.0 F; however, when selecting the output capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device. Selection of Capacitor for Soft-start (CSS) The S-1137 Series requires a capacitor for soft-start (CSS) between the SSC and VSS pins. In the all range of temperature, the S-1137 Series operates stably with a ceramic capacitor of 0.22 nF or more. By the value of this CSS, the rising speed of the output voltage is adjustable. The time that the output voltage rises to 99% is 0.7 ms (typ.), CSS = 1 nF. The recommended value for applications is 0.22 nF CSS 22 nF, however, define the values by sufficient evaluation including the temperature characteristics under the usage condition.

Refer to " Electrical Characteristics" and " Characteristics (Typical Data)" for details. VOUT1 Line regulation VIN*VOUT Indicates the dependency of the output voltage on the input voltage. That is, the values show how much the output voltage changes due to a change in the input voltage with the output current remaining unchanged. 4. 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. 5. Dropout voltage (Vdrop) Indicates the difference between input voltage VIN and the output voltage when; decreasing input voltage VIN gradually until the output voltage has dropped out to the value of 98% of output voltage VOUT3, which is at VIN = VOUT(S) + 1.0 V.

Basic operation Figure 16 shows the block diagram of S-1137 Series. The error amplifier compares the reference voltage (Vref) with Vfb, which is the output voltage resistance-divided by feedback resistors Rs and Rf. It supplies the gate voltage necessary to maintain the constant output voltage which is not influenced by the input voltage and temperature change, to the output transistor.

Output transistor In the S-1137 Series, a low on-resistance P-channel MOS FET is used as the output transistor. 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. 18 Seiko Instruments Inc. HIGH RIPPLE-REJECTION LOW DROPOUT SOFT-START FUNCTION CMOS VOLTAGE REGULATOR Rev.2.0_01 S-1137 Series 3. ON / OFF pin This pin starts and stops the regulator. When the ON / OFF pin is set to the power-off level, the entire internal circuit stops operating, and the built-in Pchannel MOS FET output transistor between the VIN and VOUT pins is turned off, reducing current consumption significantly. The S-1137 has a discharge shunt circuit which discharges the capacitor for soft-start (CSS) so that the SSC pin is forcibly set to the VSS level. Since the S-1137 Series A / B types have a built-in discharge shunt circuit to discharge the output capacitance, the VOUT pin is forcibly set to VSS level. In the S-1137 Series C / D types, the VOUT pin is set to VSS level through several hundred k internal divided resistors between the VOUT and VSS pins. Note that the current consumption increases when a voltage of 0.3 V to 1.0 V (Ta = 25C) is applied to the ON / OFF pin. The ON / OFF pin is configured as shown in Figures 17 and 18. In the S-1137 Series A / C types, the ON / OFF pin is internally pulled down to VSS in the floating status, so the VOUT pin is set to the VSS level. In the S-1137 Series B / D types, the ON / OFF pin is not internally pulled down, so do not use these types with the ON / OFF pin in the floating status. When not using the ON / OFF pin in the S-1137 Series B / D types, connect the pin to the VIN pin. Table 11 Logic Type ON / OFF Pin Internal Circuits VOUT Pin Voltage Current Consumption A/B/C/D "H": Power-on Operate Set value ISS1*1 A/B/C/D "L": Power-off Stop VSS level ISS2 *1. IC's current consumption increases as much as current flows into the pull-down resistor when the ON / OFF pin is connected to VIN and the S-1137 Series A / C types is operating (Figure 17).

Discharge shunt function (S-1137 Series A / B types) The S-1137 Series A / B types have a built-in discharge shunt circuit to discharge the output capacitance. When the ON / OFF pin is set to power-off level, turns the output transistor off, and turns the discharge shunt function on so that the output capacitor discharges. These types allow for the VOUT pin reach the VSS level faster than the S-1137 Series C / D types that does not have a discharge shunt circuit.

Parasitic diode Figure 19 5. Overcurrent protection circuit The S-1137 Series has an overcurrent protection circuit having the characteristics shown in "(1) Output Voltage vs. Output Current (When Load Current Increases) (Ta = 25C)" in " Characteristics (Typical Data)", in order to protect the output transistor against an excessive output current and short circuiting between the VOUT and VSS pins. The current (Ishort) when the output pin is short-circuited is internally set at approx. 150 mA (typ.), and the normal value is restored for the output voltage, if releasing a short circuit once. Caution Using the overcurrent protection circuit is to protect the output transistor from accidental conditions such as short circuited load and the rapid and large current flow in the large capacitor. The overcurrent protection circuit is not suitable for use under the short circuit status or large current flowing (300 mA or more) that lasts long. 6. Pull-down resistor (S-1137 Series A / C types) In the S-1137 Series A / C types, the ON / OFF pin is internally pulled down to VSS, so the VOUT pin is in the VSS level when in the floating status. IC's current consumption increases as much as current flows into the pull-down resistor of 2.2 M (typ.) when the ON / OFF pin is connected to VIN and the S-1137 Series A / C types is operating. 20 Seiko Instruments Inc. HIGH RIPPLE-REJECTION LOW DROPOUT SOFT-START FUNCTION CMOS VOLTAGE REGULATOR Rev.2.0_01 S-1137 Series 7. Soft-start function The S-1137 Series has a soft-start circuit to suppress the rush current (IRUSH) and overshoot of the output voltage generated at power-on the application or at turn-on the ON / OFF pin. After immediately power-on the application or at turn-on the ON / OFF pin, the output voltage slowly rises. The time that the output voltage rises to 99% (tSS) is adjustable by a capacitor (CSS) externally connected between the SSC and VSS pins. When CSS = 1 nF, the time is 0.7 ms (typ.). When the ON / OFF pin is off, the electric charge charged in the external capacitor (CSS) will be discharged by the discharge shunt transistor. The soft-start time (tSS) is defined by time consonants of the built-in constant current (approx. 1 A) and the external capacitor (CSS): tSS (ms) = soft-start coefficient x CSS (nF) The soft-start coefficient (25C) is as follows. Min. : 0.4, Typ. : 0.7, Max. : 1.2 Input voltage (VIN) approx.0.7 V SSC pin voltage (VSSC) VOUT x 0.99 Output voltage (VOUT) Soft-start time (tSS) t [ms] Figure 20 The rush current can be suppressed greatly by the soft-start function. As the value of the external capacitor is larger, the rush current decreases more. Figure 21 shows the waveform example of the rush current. Input voltage (VIN) Without soft-start : about 400 mA at the peak With soft-start : about 20 mA at the peak Rush current (IRUSH) t [ms] Figure 21 Waveform Example of Rush Current Seiko Instruments Inc. 21 HIGH RIPPLE-REJECTION LOW DROPOUT SOFT-START FUNCTION CMOS VOLTAGE REGULATOR Rev.2.0_01 S-1137 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), the capacitor for stabilizing the input between the VIN and VSS pins (CIN), and the capacitor for soft-start between the SSC and VSS pins, 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). * Note that the output voltage may increase due to the leakage current from a driver when a series regulator is used at high temperature. * 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. See "(8) Example of Equivalent Series Resistance vs. Output Current Characteristics (Ta = 25C)" in " Reference Data" for the equivalent series resistance (RESR) of the output capacitor. Input capacitor (CIN) : 1.0 F or more 1.0 F or more Output capacitor (CL) : Capacitor for soft-start (CSS) : 0.22 nF to 22 nF * 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. * If the output capacitance is small, power supply's fluctuation and the characteristics of load fluctuation become worse. Sufficiently evaluate the output voltage's fluctuation with the actual device. * Although this IC has a soft-start circuit, small overshoot may be included in the output voltage by the lower-valued capacitor for soft-start (CSS). Evaluate sufficiently with actual devices. * 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 Table 10 in " Electrical Characteristics" and footnote *5 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. 22 Seiko Instruments Inc.
