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) : 0.1 μF or more

Output capacitor (CL) : 0.1 μF or more (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 cap acitors are used.

 Selection of Input and Output Capacitors (CIN, CL)

The S-1313 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 0.1 μF or more over the entire temperature range.

When using an OS capacitor, tantalum capacit or, or aluminum electrolytic capacitor, the capacitance must be 0.1 μF 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 t he application.

The recommended capacitance for an application is CIN ≥ 0.1 μF, CL ≥ 0.1 μF; however, when selecting the output

capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device.

 Operation

1. Basic operation

Figure 17 shows t he block diagram of S-1313 Series.

The error amplifier compares the reference voltage (Vref) with feedback voltage (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.

2. Output transistor

In the S-1313 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.

SUPER LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR

S-1313 Series Rev.1.2_00

Seiko Instruments Inc.

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 P-

channel MOS FET output transistor between the VIN and VOUT pins is turned off, reducing current consumption

significantly.

Note that the current consumption increases when a voltage of 0.25 V to VIN − 0.3 V is applied to the ON / OFF pin. The

ON / OFF pin is configured as shown in Figures 18 and 19.

3. 1 S-1313 Series A / C types

The ON / OFF pin is internally pulled down to VSS by constant current source, so the VOUT pin is set to the VSS

level in the floating status. For the ON / OFF pin current, refer to the A / C type of ON / OFF pin input current “H” in

“ Electrical Characteristics”.

3. 2 S-1313 Series B / D types

Do not use the ON / OFF pin in the floating state because this pin is internally not pulled up or pulled down. When

not using the ON / OFF pin, connect the pin to the VIN pin.

Table 12

the ON / OFF pin is connected to VIN and the S-1313 Series A / C types is operating (refer to Figure 18).

4. Discharge shunt function (S-1313 Series A / B types)

The S-1313 Series A / B types has built-in discharge shunt circuits to discharge the output capacitance. The output

capacitance is discharged as follows so that the VOUT pin reaches the VSS level.

(1) The ON / OFF pin is set to power-off level.

(2) The output transistor is turned off.

(3) The discharge shunt circuit is turned on.

(4) The output capacitor discharges

Since the S-1313 Series C / D types does not have discharge shunt circuits, the VOUT pin is set to VSS level through

several hundred kΩ internal divided resistors between the VOUT and VSS pins. The S-1313 Series A / B types allow

for the VOUT pin reach the VSS level rapidly due to the discharge shunt circuits.

5. Constant current source pull-down (S-1313 Series A / C types)

The ON / OFF pin is internally pulled down to VSS by constant current source, so the VOUT pin is set to the VSS level

in the floating status.

Note that the IC’s current consumption increases as much as current flows into the constant current of 0.1 μA typ. when

the ON / OFF pin is connected to VIN and the S-1313 Series A / C types is operating.

SUPER LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR

S-1313 Series Rev.1.2_00

6. Overcurrent protection circuit

The S-1313 Series has an overcurrent protection circuit having the characteristics shown in “1. Output Voltage vs.

Output Current (When Load Current Increases) (Ta = +25°C)” 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. 50 mA t yp., 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

flow ing (240 mA or more) that lasts long.

7. Thermal shutdown circuit

The S-1313 Series has a thermal shutdown circuit to protect the device from damage due to overheat. When the

junction temperature rises to 150°C typ., the thermal shutdown circuit operates to stop regulating. When the junction

temperature drops to 120°C typ., the thermal shutdown circuit is released to restart regulating.

Due to self-heating of the S-1313 Series, if the thermal shutdown circuit start s operating, it st ops regulating so t hat t he

output voltage drops. When regulation stops, the S-1313 Series does not itself generate heat and the IC’s

temperature drops. When the temperature drops, the thermal shutdown circuit is released to restart regulating, thus

this IC generates heat again. Repeating this procedure makes the waveform of the output voltage into a pulse-like

form. Stop or restart of regulation cont inues unless decreasing either both of the input voltage and the out put voltage

in order to reduce the internal current consumpt ion, or decreasing the ambient temperature.

Table 13

Thermal Shutdown Circuit VOUT Pin Voltage

Operate : 150°C typ.*1 VSS level

Release : 120°C typ.*1 Set value

*1. Junction temperature

8. Thermal shutdown circuit stop function

The 1313 Series has a thermal shutdown circuit stop function during low load current.

When the load current is approximately 0.2 mA typ. or less, the current t hat flows in the thermal shutdown circuit is

possible.

When the load current is approximately 0.5 mA typ. or more, a current is applied t o t he thermal shutdown circuit, thus

making the protect operation possible.

 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 the 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 (10 μA or less).

• Not e that the output voltage may increase due to the leakage current from a driver when a series regulator is used at

high temperature.

• Note that the output voltage may increase due to the leakage current from a driver even if the ON / OFF pin is at the

power-off level when a series regulator is used at a 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 “5. Example of Equivalent Series

Resistance vs. Output Current Characteristics (Ta = +25°C)” in “ Reference Data” for the equivalent series

resistance (RESR) of the output capacitor.

Input capacitor (CIN) : 0.1 μF or more

Output capacitor (CL) : 0.1 μF or more

• 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.

• Ringing may occur when these three conditions below are satisfied. Before selecting an input capacitor, be sure to

evaluate sufficiently under the actual usage conditions, including the temperature characteristics.

The power supply inductance is high.

The load current is 100 mA or more.

The difference between the input voltage and the output voltage is close to the value of dropout voltage.

• If the output capacitance is small, power supply’s fluctuation and t he characteristics of load fluctuation become worse.

Sufficiently evaluate the output voltage’s fluct uation with the actual device.

• A momentary overshoot may be output when the power supply suddenly increases, and the output capacitance is

small. It is therefore important to sufficiently evaluate the output voltage at power application in actual device.

• The application conditions for t he input volt age, out put volt age, 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 11 in “

Electrical Characteristics” and f ootnote *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.
