Rev.4.1_02
The S-1131 Series is a positive voltage regulator with a low dropout voltage, high-accuracy output voltage, and
low current consumption developed based on CMOS technology.
A built-in low on-resistance transistor provides a low dropout voltage and large output current, and a built-in
overcurrent protection circuit prevents the load current from exceeding the current capacitance of the output
transistor. An ON/OFF circuit ensures a long battery life, and small SOT-89-3, SOT-89-5 and 6-Pin HSON(A)
packages realize high-density mounting.

Explanation of Terms
1. Low dropout voltage regulator
This voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor.
2. Output voltage (VOUT
)
The accuracy of the output voltage is ensured at 1.0% under the specified conditions of fixed input
voltage*1, fixed output current, and fixed temperature.
*1. Differs depending the product.
Caution If the above conditions change, the output voltage value may vary and exceed the
accuracy range of the output voltage. Refer to " Electrical Characteristics" and "
Characteristics (Typical Data)" for details.
VOUT1
3. Line regulation
V V
OUT
IN
Indicates the dependency of the output voltage on the input voltage. That is, the value shows how much
the output voltage changes due to a change in the input voltage with the output current remaining
unchanged.
4. Load regulation (VOUT2
)
Indicates the dependency of the output voltage on the output current. That is, the value shows how
much the output voltage changes due to a change in the output current with the input voltage remaining
unchanged.
5. Dropout voltage (Vdrop
)
Indicates the difference between input voltage (VIN1) and the output voltage when; decreasing input
voltage (VIN) gradually until the output voltage has dropped out to the value of 98% of output voltage
(VOUT3), which is at VIN = VOUT(S) 1.0 V.
Vdrop = VIN1 (VOUT3 0.98)

Operation
1. Basic operation
Figure 13 shows the block diagram of the S-1131 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-1131 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
In case of product with ON/OFF circuit, 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. The VOUT pin becomes the Vss level due to the internally divided
resistance of several hundreds k between the VOUT pin and the VSS pin.
The structure of the ON/OFF pin is as shown in Figure 14. Since the ON/OFF pin is neither pulled down
nor pulled up internally, do not use it in the floating states. In addition, note that the current consumption
increases if a voltage of 0.3 V to VIN – 0.3 V is applied to the ON/OFF pin. When not using the ON/OFF
pin, connect it to the VSS pin in the product A type, and connect it to the VIN pin in B type.

Selection of Output Capacitor (CL)
The S-1131 Series performs phase compensation using the internal phase compensator in the IC and the
ESR (Equivalent Series Resistance) of the output capacitor to enable stable operation independent of
changes in the output load. Therefore, always place a capacitor (CL) of 2.2 F or more between the VOUT
pin and the VSS pin.
For stable operation of the S-1131 Series, it is essential to employ a capacitor whose ESR is within an
optimum range. Using a capacitor whose ESR is outside the optimum range (approximately 0.5 to 5 ),
whether larger or smaller, may cause an unstable output, resulting in oscillation. For this reason, a tantalum
electrolytic capacitor is recommended.
When a ceramic capacitor or an OS capacitor with a low ESR is used, it is necessary to connect an
additional resistor that serves as the ESR in series with the output capacitor. The required resistance value
is approximately 0.5 to 5 , which varies depending on the usage conditions, so perform sufficient
evaluation for selection. Ordinarily, around 1.0 is recommended.
Note that an aluminum electrolytic capacitor may increase the ESR at a low temperature, causing
oscillation. When using this kind of capacitor, perform thorough evaluation, including evaluation of
temperature characteristics.

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 a 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
(1.0 mA or less).
The S-1131 Series performs phase compensation by using an internal phase compensator and the ESR
of an output capacitor. Therefore, always place a capacitor of 2.2 F or more between the VOUT pin
and the VSS pin. A tantalum type capacitor is recommended. Moreover, to secure stable operation of
the S-1131 Series, it is necessary to employ a capacitor with an ESR within an optimum range (0.5 to
5 ). Using a capacitor whose ESR is outside the optimum range (approximately 0.5 to 5 ), whether
larger or smaller, may cause an unstable output, resulting in oscillation. Perform sufficient evaluation
under the actual usage conditions for selection, including evaluation of temperature characteristics.
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.
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
6 in “ Electrical Characteristics” and footnote *5 of the table.
