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):
Output capacitor (CL):
0.1 μF or more
Unnecessary, or an output capacitor which is 10 μF or less.
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-1315 Series does not require an output capacitor between the VOUT pin and the VSS pin for phase
compensation. Operation is stabilized even without an output capacitor over the entire temperature range. If the
capacitor is used, the operation is stabilized with a ceramic capacitor which is CL ≤ 10 μF in the same way. Moreover,
when using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capacitor, the capacitance must be 10 μF
or less.
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 ≥ 0.1 μF; however, when selecting the output capacitor, perform
sufficient evaluation, including evaluation of temperature characteristics, on the actual device.

Operation
1. Basic operation
Figure 16 shows the block diagram of the S-1315 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-1315 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 reverse
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 1.0 V is applied to the ON / OFF pin.
The ON / OFF pin is configured as shown in Figure 17 and Figure 18.
3. 1 S-1315 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 ON / OFF pin input current "H" in " Electrical
Characteristics".
3. 2 S-1315 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.

4. Discharge shunt function (S-1315 Series A / B type)
The S-1315 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-1315 Series C / D type does not have a discharge shunt circuit, the VOUT pin is set to the VSS level
through several MΩ internal divided resistors between the VOUT pin and the VSS pin. The S-1315 Series A / B type
allows the VOUT pin to reach the VSS level rapidly due to the discharge shunt circuit.

5. Constant current source pull-down (S-1315 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 constant current of 0.1 μA typ.
when the ON / OFF pin is connected to the VIN pin.

6. Overcurrent protection circuit
The S-1315 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 (Ishort) when the output pin is short-circuited 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 of the
package.

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 the 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 (0.1 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-1315 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):
Output capacitor (CL):
0.1 μF or more
Unnecessary or an output capacitor which is 10 μF or less.
• 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.
• Output voltage noise may increase when the output current is low.
• The application conditions for the input voltage, the output voltage, and the 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 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.
