Caution The above connection diagram and constants will not guarantee successful operation. Perform
thorough evaluation using the actual application to set the constants.
Condition of Application
Input capacitor (CIN): 0.22 μF or more
Output capacitor (CL): 0.22 μF or more
Caution Generally a series regulator may cause oscillation, depending on the selection of external parts.
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-1312xxxH Series requires an output capacitor between the VOUT pin and the VSS pin for phase compensation.
Operation is stabilized by a ceramic capacitor with an output capacitance of 0.22 μF or more over the entire temperature
range. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capacitor, the capacitance must
be 0.22 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 the application.
The recommended capacitance for an application is CIN ≥ 0.22 μF, CL ≥ 0.22 μF; however, when selecting the output
capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device.

Explanation of Terms
1. Low dropout voltage regulator
This voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor.
2. Output voltage (VOUT)
The accuracy of the output voltage is ensured at ±1.0% or ±15 mV*1 under the specified conditions of fixed input
voltage*2, fixed output current, and fixed temperature.
*1. When VOUT < 1.5 V: ±15 mV, when VOUT ≥ 1.5 V: ±1.0%
*2. 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. Refer to " Electrical Characteristics" and " Characteristics (Typical Data)"
for details.

Operation
1. Basic operation
Figure 14 shows the block diagram of the S-1312xxxH 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-1312xxxH 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, when the potential of VOUT became higher
than VIN.

3. ON / OFF pin
This pin starts and stops the regulator.
When the ON / OFF pin is set to OFF level, the entire internal circuit stops operating, and the built-in
P-channel MOS FET output transistor between the VIN pin and the VOUT pin 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 Figure 15 and Figure 16.
3. 1 S-1312xxxH Series A / C type
The ON / OFF pin is internally pulled down to the VSS pin in the floating status, so the VOUT pin is set to the VSS
level.
For the ON / OFF pin current, refer to the A / C type of the ON / OFF pin input current "H" in " Electrical
Characteristics".
3. 2 S-1312xxxH Series B / D type
The ON / OFF pin is internally not pulled up or pulled down, so do not use this pin in the floating status. When not
using the ON / OFF pin, connect the pin to the VIN pin.
Table 12
Product Type ON / OFF Pin Internal Circuit VOUT Pin Voltage Current Consumption
A / B / C / D "H": ON Operate Set value ISS1*1
A / B / C / D "L": OFF Stop VSS level ISS2
*1. Note that the IC's current consumption increases as much as current flows into the pull-down resistor when
the ON / OFF pin is connected to the VIN pin and the S-1312xxxH Series A / C type is operating (refer to
Figure 15).

4. Discharge shunt function (S-1312xxxH Series A / B type)
The S-1312xxxH Series A / B type has a built-in discharge shunt circuit 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 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-1312xxxH Series C / D type does not have a discharge shunt circuit, the VOUT pin is set to the VSS level
through several hundred kΩ internal divided resistors between the VOUT pin and the VSS pin. The S-1312xxxH Series
A / B type allows the VOUT pin to reach the VSS level rapidly due to the discharge shunt circuit.

5. Pull-down resistor (S-1312xxxH Series A / C type)
The ON / OFF pin is internally pulled down to the VSS pin in the floating status, so the VOUT pin is set to the VSS level.
Note that the IC's current consumption increases as much as current flows into the pull-down resistor of 2.2 MΩ typ.
when the ON / OFF pin is connected to the VIN pin and the S-1312xxxH Series A / C type is operating.

6. Overcurrent protection circuit
The S-1312xxxH Series includes 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 pin
and the VSS pin. The current when the output pin is short-circuited (Ishort) is internally set at approx. 50 mA typ., and
the normal value is restored for the output voltage, if releasing a short circuit once.
Caution This overcurrent protection circuit does not work as for thermal protection. If this IC long keeps
short circuiting inside, pay attention to the conditions of input voltage and load current so that,
under the usage conditions including short circuit, the loss of the IC will not exceed power
dissipation.
7. Thermal shutdown circuit
The S-1312xxxH 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-1312xxxH Series, if the thermal shutdown circuit starts operating, it stops regulating so
that the output voltage drops. When regulation stops, the S-1312xxxH 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 the S-1312xxxH Series generates heat again. Repeating this procedure makes the waveform of the output
voltage into a pulse-like form. Stop or restart of regulation continues unless decreasing either or both of the input
voltage and the output current in order to reduce the internal power consumption, or decreasing the ambient
temperature.

Precautions
• Wiring patterns for the VIN pin, the VOUT pin and GND should be designed so that the impedance is low. When
mounting an output capacitor between the VOUT pin and the VSS pin (CL) and a capacitor for stabilizing the input
between the VIN pin and the VSS pin (CIN), the distance from the capacitors to these pins should be as short as
possible.
• Note that generally the output voltage may increase when a series regulator is used at low load current (1.0 mA or
less).
• Note that generally the output voltage may increase due to the leakage current from an output driver when a series
regulator is used at high temperature.
• Note that the output voltage may increase due to the leakage current from an output driver even if the ON / OFF pin is
at OFF level 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 the S-1312xxxH Series. However, be sure to perform sufficient evaluation under the
actual usage conditions for selection, including evaluation of temperature characteristics. Refer to "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): 0.22 μF or more
Output capacitor (CL): 0.22 μF or more
• The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitance 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.
• Overshoot may occur in the output voltage momentarily if the voltage is rapidly raised at power-on or when the power
supply fluctuates. Sufficiently evaluate the output voltage at power-on with the actual device.
• The application conditions for the input voltage, the output voltage, and the load current should not exceed the 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 footnote *5 of the table.
• ABLIC Inc. 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.
