*1. VOUT(S): Set output voltage
VOUT(E): Actual output voltage
The output voltage when VIN = VOUT(S) + 1.0 V, IOUT = 30 mA
*2. The output current at which the output voltage becomes 95% of VOUT(E) after gradually increasing the output current.
*3. Vdrop = VIN1 − (VOUT3 × 0.98)
VIN1 is the input voltage at which the output voltage becomes 98% of VOUT3 after gradually decreasing the input
voltage.
VOUT3 is the output voltage when VIN = VOUT(S) + 1.0 V, and IOUT = 100 mA.
*4. A change in the temperature of the output voltage [mV/°C] is calculated using the following equation.
ΔVOUT
ΔVOUT
[mV/°C]*1 = VOUT(S) [V]*2 × ΔTa•VOUT [ppm/°C]*3 ÷ 1000
ΔTa
*1. Change in temperature of output voltage
*2. Set output voltage
*3. Output voltage temperature coefficient
*5. Due to limitation of the power dissipation, this value may not be satisfied. Attention should be paid to the power
dissipation when the output current is large.
This specification is guaranteed by design.

Caution
The above connection diagram and constant will not guarantee successful operation. Perform
thorough evaluation including the temperature characteristics with an actual application to set the
constant.
Condition of Application
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.
Caution 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-1324 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-1324 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 16 shows the block diagram of the S-1324 Series to describe the basic operation.
The error amplifier output voltage (Verror) is divided by the feedback resistors (Rs and Rf). In order to keep the
feedback voltage (Vfb) equal to the reference voltage (Vref), the error amplifier outputs Verror. The preamplifier controls
the output transistor to keep Verror equal to the output voltage (VOUT), and consequently, the regulator starts the
operation that holds VOUT constant without the influence of the input voltage (VIN).

2. Output transistor
In the S-1324 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 hold 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.
The internal equivalent circuit related to the ON / OFF pin is configured as shown in Figure 17 and Figure 18. Note
that the current consumption increases when a voltage of VSL max.*1 to VIN − 0.3 V is applied to the ON / OFF pin.
3. 1 S-1324 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 pulled down
to VSS.
3. 2 S-1324 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.

4. Discharge shunt function (S-1324 Series A / B type)
The S-1324 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-1324 Series C / D type does not have a discharge shunt circuit, the VOUT pin is set to VSS level through
constant current load between the VOUT pin and the VSS pin. The S-1324 Series A / B type allows the VOUT pin to
reach the VSS level rapidly due to the discharge shunt circuit.

level.

6. Overcurrent protection circuit
The S-1324 Series has a built-in overcurrent protection circuit to limit the overcurrent of the output transistor. When
the VOUT pin is shorted with 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-1324 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.
7. Thermal shutdown circuit
The S-1324 Series has a built-in thermal shutdown circuit to limit overheating. When the junction temperature
increases to 150°C typ., the thermal shutdown circuit becomes the detection status, and the regulating is stopped.
When the junction temperature decreases to 120°C typ., the thermal shutdown circuit becomes the release status,
and the regulator is restarted.
If the thermal shutdown circuit becomes the detection status due to self-heating, the regulating is stopped and VOUT
decreases. For this reason, the self-heating is limited and the temperature of the IC decreases. The thermal
shutdown circuit becomes release status when the temperature of the IC decreases, and the regulating is restarted,
thus the self-heating is generated again. Repeating this procedure makes the waveform of VOUT into a pulse-like form.
This phenomenon 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. Note that the product may suffer
physical damage such as deterioration if the above phenomenon occurs continuously.
Caution 1. When the heat radiation of the application is not in a good condition, the self-heating cannot be
limited immediately, and the IC may suffer physical damage. Perform thorough evaluation
including the temperature characteristics with an actual application to confirm no problems
happen.
2. If a large load current flows during the restart process of regulating after the thermal shutdown
circuit changes to the release status from the detection status, the thermal shutdown circuit
becomes the detection status again due to self-heating, and a problem may happen in the restart
of regulating. A large load current, for example, occurs when charging to the CL whose
capacitance is large.
Perform thorough evaluation including the temperature characteristics with an actual application
to select CL.

Precautions
• Generally, when a voltage regulator is used under the condition that the load current value is small (10 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 the ON / OFF pin is used under the condition of OFF, 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-1324 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, an overshoot may occur in the output voltage momentarily if the input voltage steeply
changes when the input voltage is started up, the soft-start operation is performed, the input voltage fluctuates etc.
Perform thorough evaluation including the temperature characteristics with an actual application to confirm no
problems happen.
• 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.
• If the input voltage is started up steeply under the condition that the capacitance of CL is large, the thermal shutdown
circuit may be in the detection status by self-heating due to the charge current to CL.
• 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 12 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.
