5.5 V INPUT, 150 mA VOLTAGE REGULATOR
WITH REVERSE CURRENT PROTECTION
Rev.1.4_00
© ABLIC Inc., 2012-2023
The S-13R1 Series, developed by using the CMOS technology, is a positive voltage regulator IC of 150 mA output current,
which has low dropout voltage, high-accuracy output voltage and low current consumption.
Even with low current consumption of 5 μA typ., it has high ripple-rejection of 70 dB typ., and a ceramic capacitor of 1.0 μF
or more can be used as the input and output capacitors.
The S-13R1 Series includes an overcurrent protection circuit that prevents the load current from exceeding the current
capacity of the output transistor and a thermal shutdown circuit that prevents damage because of overheating.
Due to the built-in reverse current protection function, the reverse current flowing from the VOUT pin to the VIN pin can be
controlled as the small value 0.09 μA max. Therefore, IC protection diode is not needed.

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):
1.0 μF or more
1.0 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-13R1 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 1.0 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 1.0 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 ≥ 1.0 μF, CL ≥ 1.0 μF; however, when selecting the output

Operation
1. Basic operation
Figure 18 shows the block diagram of the S-13R1 Series.
The error amplifier compares the reference voltage (Vref) with feedback voltage (Vfb), which is the output voltage
resistance-divided by feedback resistors (Rs, 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-13R1 Series, a low on-resistance P-channel MOS FET is used as the output transistor.
Since there exists a parasitic diode between the VIN pin and the VOUT pin, the reverse current arises when potential
of VOUT becomes higher than VIN. However, the reverse current detection circuit prevents the current from flowing from
the VOUT pin in the S-13R1 Series. Therefore, the IC is not damaged even when the potential of VOUT becomes 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 0.3 V to 1.0 V is applied to the ON / OFF pin. The
ON / OFF pin is configured as shown in Figure 19 and Figure 20.
3. 1 S-13R1 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.
3. 2 S-13R1 Series B / D type
The ON / OFF pin is not internally pulled down to the VSS pin, 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-13R1 Series A / B type)
The S-13R1 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-13R1 Series C / D type does not have a discharge shunt circuit, the VOUT pin is not discharged. The
S-13R1 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-13R1 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 pin and the
VSS pin. The current (Ishort) when the output pin is short-circuited is internally set at approx. 30 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.
7. Thermal shutdown circuit
The S-13R1 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-13R1 Series, if the thermal shutdown circuit starts operating, it stops regulating so that
the output voltage drops. When regulation stops, the S-13R1 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-13R1 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.

8. Reverse current protection function
8. 1 Detection and release of reverse current protection mode
The reverse current protection function compares values of the VIN pin voltage (VIN) and the VOUT pin voltage
(VOUT), and prevents the current from flowing to the VIN pin and the VSS pin from the VOUT pin. Also, in the
S-13R1 Series A / B type, the current flows from the VOUT pin to the VSS pin due to a discharge shunt circuit.
During the reverse current protection mode, the connection direction of parasitic diode of the output transistor is
switched by the reverse current protection circuit, and the feedback resistors (Rs, Rf) and the VSS pin are
disconnected.
The reverse current is prevented by switching the reverse current protection mode before VIN becomes lower than
VOUT.
As shown in Figure 24, in the case of VIN − VOUT > VREVD, the S-13R1 Series is in normal operation mode. The
reverse current protection mode is detected when VIN − VOUT ≤ VREVD.
In order to insure the stable operation, there is also a hysteresis for detection and release of the reverse current
protection mode. Therefore, the reverse current protection mode is released when V IN − VOUT ≥ VREVR.
The reverse current detection circuit operates at 0 V ≤ VIN ≤ 5.5 V and VOUT ≥ 0.5 V.

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 (10 μA or
less).
If the S-13R1 Series is used at low load current (several hundred nA), the output voltage may increase due to the
leakage current from an output driver at high temperature, and the reverse current protection mode may not be
released. Perform sufficient evaluation with the actual device in use.
• 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-13R1 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):
1.0 μF or more
1.0 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
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 12 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.
