The S-1137 Series, developed using the CMOS technology, is a positive voltage regulator IC which has the low dropout
voltage, the high-accuracy output voltage and the soft-start function (300 mA output current).
A 1.0 μF small ceramic capacitor can be used. It operates with low current consumption of 45 μA typ.
The overcurrent protection circuit prevents the load current from exceeding the current capacity of the output transistor.
The ON / OFF circuit ensures longer battery life.
Compared to the conventional CMOS technology regulator ICs, various capacitors including small ceramic capacitors can be
used for this IC.
Furthermore, small SOT-89-5, SOT-23-5, and SNT-6A(H) packages realize high-density mounting.

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) : 1.0 μF or more
Output capacitor (CL) : 1.0 μF or more
Capacitor for soft-start (CSS) : 0.22 nF to 22 nF
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-1137 Series requires an output capacitor between the VOUT pin and 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
capacitor, perform sufficient evaluation including evaluation of temperature characteristics with the actual device.
Selection of Capacitor for Soft-start (CSS)
The S-1137 Series requires a capacitor for soft-start (CSS) between the SSC pin and VSS pin. Over the entire
temperature range, the S-1137 Series operates stably with a ceramic capacitor of 0.22 nF or more. According to CSS
capacitance, the rising speed of the output voltage is adjustable. The time that the output voltage rises to 99% is 0.7 ms
typ. at CSS = 1.0 nF. The recommended value for applications is 0.22 nF CSS 22 nF, however, define the values by
sufficient evaluation including the temperature characteristics under the usage condition.

Operation
1. Basic operation
Figure 16 shows the block diagram of the S-1137 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-1137 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 VOUT pin is turned off, reducing current consumption significantly. The
S-1137 Series has a discharge shunt circuit which discharges the capacitor for soft-start (CSS) so that the SSC pin is
forcibly set to the VSS level.
Since the S-1137 Series A / B types have a built-in discharge shunt circuit to discharge the output capacitance, the
VOUT pin is forcibly set to VSS level. In the S-1137 Series C / D types, the VOUT pin is set to VSS level through several
hundred kΩ internal divided resistors between the VOUT pin and VSS pin.
Note that the current consumption increases when a voltage of 0.3 V to 1.0 V (Ta = 25°C) is applied to the ON / OFF
pin. The ON / OFF pin is configured as shown in Figures 17 and 18. In the S-1137 Series A / C types, 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. In the S-1137
Series B / D types, the ON / OFF pin is not internally pulled down, so do not use the pin in the floating status. When not
using the ON / OFF pin in the S-1137 Series B / D types, connect the pin to the VIN pin.

4. Discharge shunt function (S-1137 Series A / B types)
The S-1137 Series A / B types have a built-in discharge shunt circuit to discharge the output capacitance. When the
ON / OFF pin is set to OFF level, turns the output transistor off, and turns the discharge shunt circuit on so that the
output capacitor discharges. These types allow for the VOUT pin reach the VSS level faster than the S-1137 Series C /
D types that does not have a discharge shunt circuit.

5. Overcurrent protection circuit
The S-1137 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 VSS
pin. The current when the output pin is short-circuited (Ishort) is internally set at approx. 150 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.
6. Pull-down resistor (S-1137 Series A / C types)
In the S-1137 Series A / C types, 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.
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-1137 Series A / C types is operating.

7. Soft-start function
The S-1137 Series has a soft-start circuit to suppress the rush current (IRUSH) and overshoot of the output voltage
generated at power-on or at the time when the ON / OFF pin is set to ON.
Immediately after power-on or after the ON / OFF pin is set to ON, the output voltage slowly rises. The time that the
output voltage rises to 99% (tSS) is adjustable by a capacitor (CSS) externally connected between the SSC pin and VSS
pin. When CSS = 1.0 nF, the time is 0.7 ms typ. At the time when the ON / OFF pin is set to OFF, the electric charge
charged in the external capacitor (CSS) will be discharged by the discharge shunt transistor.
The soft-start time (tSS) is defined by time consonants of the built-in constant current (approx. 1 μA) and the external
capacitor (CSS):
tSS (ms) = soft-start coefficient × CSS (nF)
The soft-start coefficient (25°C) is as follows.
Min. : 0.4, Typ. : 0.7, Max. : 1.2

The rush current can be suppressed greatly by the soft-start function.
As the value of the external capacitor is larger, the rush current decreases more.
Figure 21 shows the waveform example of the rush current.

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 VSS pin (CL), the capacitor for stabilizing the input between
the VIN pin and VSS pin (CIN), and the capacitor for soft-start between the SSC pin and VSS pin, 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.
Generally a series regulator may cause oscillation, depending on the selection of external parts. The following
conditions are recommended for the S-1137 Series. However, be sure to perform sufficient evaluation under the actual
usage conditions for selection, including evaluation of temperature characteristics. Refer to “(8) 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) : 1.0 μF or more
Output capacitor (CL) : 1.0 μF or more
Capacitor for soft-start (CSS) : 0.22 nF to 22 nF
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.
Although the S-1137 Series has a soft-start circuit, overshoot may occur in the output voltage momentarily when the
capacitance of the capacitor for soft-start (CSS) is small. Perform sufficient evaluation with actual devices.
The application conditions for the input voltage, output voltage, and 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 10 in
Electrical Characteristics” and footnote *5 of the table.
