Caution
The above connection diagram and constants will not guarantee successful operation.
Perform thorough evaluation including the temperature characteristics with an actual application to
set the constants.
Condition of Application
Input capacitor (CIN):
Output capacitor (CL):
Caution
A ceramic capacitor with capacitance of 1.0 μF or more is recommended.
A ceramic capacitor with capacitance of 1.0 μF or more is recommended.
Generally, in a voltage regulator, an oscillation may occur depending on the selection of the external
parts. Perform thorough evaluation including the temperature characteristics with an actual
application using the above capacitors to confirm no oscillation occurs.
Selection of Input Capacitor (CIN) and Output Capacitor (CL)
The S-1318 Series requires CL between the VOUT pin and the VSS pin for phase compensation. The operation is
stabilized by a ceramic capacitor with capacitance of 1.0 μF or more. When using an OS capacitor, a tantalum capacitor
or an aluminum electrolytic capacitor, the capacitance also must be 1.0 μF or more. However, an oscillation may occur
depending on the equivalent series resistance (ESR).
Moreover, the S-1318 Series requires CIN between the VIN pin and the VSS pin for a stable operation.
Generally, an oscillation may occur when a voltage regulator is used under the conditon that the impedance of the power
supply is high.
Note that the output voltage transient characteristics vary depending on the capacitance of CIN and CL and the value of
ESR.
Caution Perform thorough evaluation including the temperature characteristics with an actual application to
select CIN and CL.

Operation
1. Basic operation
Figure 13 shows the block diagram of the S-1318 Series to describe the basic operation.
The error amplifier compares the feedback voltage (Vfb) whose output voltage (VOUT) is divided by the feedback
resistors (Rs and Rf) with the reference voltage (Vref). The error amplifier controls the output transistor, consequently,
the regulator starts the operation that keeps VOUT constant without the influence of the input voltage (VIN).

2. Output transistor
In the S-1318 Series, a low on-resistance P-channel MOS FET is used between the VIN pin and the VOUT pin as
the output transistor. In order to keep VOUT constant, the ON resistance of the output transistor varies appropriately
according to the output current (IOUT).
Caution Since a parasitic diode exists between the VIN pin and the VOUT pin due to the structure of the
transistor, the IC may be damaged by a reverse current if VOUT becomes higher than VIN. Therefore,
be sure that VOUT does not exceed VIN + 0.3 V.

3. ON / OFF pin
The ON / OFF pin controls the internal circuit and the output transistor in order to start and stop the regulator. When
the ON / OFF pin is set to OFF, the internal circuit stops operating and the 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 14 and Figure 15.
3. 1 S-1318 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-1318 Series B / D type
The ON / OFF pin is not internally pulled down to the VSS pin, so do not use it in the floating status. When not
using the ON / OFF pin, connect it to the VIN pin.

*2. 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 the VIN pin and the S-1318 Series A / C type is
operating (refer to Figure 14).
*3. The VOUT pin voltage of the S-1318 Series A / B type is pulled down to VSS due to combined resistance
(RLOW = 35 Ω typ.) of the discharge shunt circuit and the feedback resistors, and a load.

4. Discharge shunt function (S-1318 Series A / B type)
The S-1318 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-1318 Series C / D type does not have a discharge shunt circuit, the VOUT pin is set to VSS level through
several MΩ internal divided resistors between the VOUT pin and the VSS pin. The S-1318 Series A / B type allows the
VOUT pin to reach the VSS level rapidly due to the discharge shunt circuit.

6. Overcurrent protection circuit
The S-1318 Series has a built-in overcurrent protection circuit to limit the overcurrent of the output transistor.
When the VOUT pin is shorted to the VSS pin, that is, at the time of the output short-circuit, the output current is
limited to 50 mA typ. due to the overcurrent protection circuit operation. The S-1318 Series restarts regulating
when the output transistor is released from the overcurrent status.
Caution This overcurrent protection circuit does not work as for thermal protection. For example, when
the output transistor keeps the overcurrent status long at the time of output short-circuit or due
to other reasons, pay attention to the conditions of the input voltage and the load current so as
not to exceed the power dissipation.

Precautions
• Generally, when a voltage regulator is used under the condition that the load current value is small (1 μA or less), the
output voltage may increase due to the leakage current of an output transistor.
• Generally, when a voltage regulator is used under the condition that the temperature is high, the output voltage may
increase due to the leakage current of an output transistor.
• Generally, when a voltage regulator is used under the condition that the impedance of the power supply is high, an
oscillation may occur. Perform thorough evaluation including the temperature characteristics with an actual application
to select CIN.
• Generally, in a voltage regulator, an oscillation may occur depending on the selection of the external parts. The
following use conditions are recommended in the S-1318 Series, however, perform thorough evaluation including the
temperature characteristics with an actual application to select CIN and CL.
Input capacitor (CIN):
Output capacitor (CL):
A ceramic capacitor with capacitance of 1.0 μF or more is recommended.
A ceramic capacitor with capacitance of 1.0 μF or more is recommended.
• Generally, in a voltage regulator, the values of an overshoot and an undershoot in the output voltage vary depending
on the variation factors of input voltage start-up, input voltage fluctuation and load fluctuation etc., or the capacitance
of CIN or CL and the value of the equivalent series resistance (ESR), which may cause a problem to the stable
operation. Perform thorough evaluation including the temperature characteristics with an actual application to select
CIN and CL.
• Generally, in a voltage regulator, if the VOUT pin is steeply shorted with GND, a negative voltage exceeding the
absolute maximum ratings may occur in the VOUT pin due to resonance phenomenon of the inductance and the
capacitance including CL on the application. The resonance phenomenon is expected to be weakened by inserting a
series resistor into the resonance path, and the negative voltage is expected to be limited by inserting a protection
diode between the VOUT pin and the VSS pin.
• Make sure of the conditions for the input voltage, output voltage and the load current so that the internal loss does 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.
• When considering the output current value that the IC is able to output, make sure of the output current value specified
in Table 11 in " Electrical Characteristics" and footnote *5 of the table.
• Wiring patterns on the application related to the VIN pin, the VOUT pin and the VSS pin should be designed so that the
impedance is low. When mounting CIN between the VIN pin and the VSS pin and CL between the VOUT pin and the
VSS pin, connect the capacitors as close as possible to the respective destination pins of the IC.
• In the package equipped with heat sink of backside, mount the heat sink firmly. Since the heat radiation differs
according to the condition of the application, perform thorough evaluation with an actual application to confirm no
problems happen.
• 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.
