HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT
CMOS VOLTAGE REGULATOR
S-1132 Series
The S-1132 Series is a positive voltage regulator with a low
dropout voltage, high output voltage accuracy, and low
current consumption (300 mA output current) developed
based on CMOS technology.
A 0.1 µF small ceramic capacitor can be used. It operates
with low current consumption of 20 µA typ.
A built-in Output current protector prevents the load current
from exceeding the current capacitance of the output
transistor.
Compared with the conventional 300 mA output current
CMOS voltage regulators, high-density mounting is realized
by using the super-small SNT-6A(H) package and a 0.1µF
small ceramic capacitor.
Also, the low current consumption makes the S-1132 series
ideal for mobile devices.

A general series regulator may oscillate, depending on the external components selected. Check
that no oscillation occurs with the application using the above capacitor.
„ Selection of Input and Output Capacitors (CIN, CL)
The S-1132 Series requires an output capacitor between the VOUT and VSS pins for phase compensation. Operation is
stabilized by a ceramic capacitor with an output capacitance of 0.1 µF or more in the entire temperature range. However,
when using an OS capacitor, tantalum capacitor, or aluminum electrolytic capacitor, a ceramic capacitor with a capacitance
of 0.1 µF or more and an ESR of 2.0 Ω or less is required.
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 value for an application is 0.1 µF or more for CIN and 0.1 µF or more for CL; however, when selecting the
output capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device.

„ Explanation of Terms
1. Low dropout voltage regulator
The low dropout voltage regulator is a voltage regulator whose dropout voltage is low due to its built-in low onresistance transistor.
2. Low ESR
A capacitor whose ESR (Equivalent Series Resistance) is low. The S-1132 Series enables use of a low ESR
capacitor, such as a ceramic capacitor, for the output-side capacitor CL. A capacitor whose ESR is 2.0 Ω or less can
be used.
3. 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 on the product.
Caution If the above conditions change, the output voltage value may vary and exceed the accuracy range
of the output voltage. Please see the electrical characteristics and attached characteristics data
for details.

4. Line regulation 

Indicates the dependency of the output voltage on the input voltage. That is, the values show how much the output

5. Load regulation (∆VOUT2)
Indicates the dependency of the output voltage on the output current. That is, the values show how much the output
voltage changes due to a change in the output current with the input voltage remaining unchanged.
6. Dropout voltage (Vdrop)
Indicates the difference between the input voltage VIN1, which is the input voltage (VIN) at the point where the output
voltage has fallen to 98% of the output voltage value VOUT3 after VIN was gradually decreased from VIN = VOUT(S) +
1.0 V, and the output voltage at that point (VOUT3 × 0.98).

„ Operation
1. Basic operation
Figure 13 shows the block diagram of the S-1132 Series.
The error amplifier compares the reference voltage (Vref) with Vfb, which is the output voltage resistance-divided by
feedback resistors Rs and Rf. It supplies the output transistor with the gate voltage necessary to ensure a certain
output voltage free of any fluctuations of input voltage and temperature.

2. Output transistor
The S-1132 Series uses a low on-resistance P-channel MOS FET 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 inverse
current flowing from the VOUT pin through a parasitic diode to the VIN pin.

3. Shutdown pin (ON/OFF pin)
This pin starts and stops the regulator.
When the ON/OFF pin is set to the shutdown level, the operation of all internal circuits stops, and the built-in P-channel
MOS FET output transistor between the VIN pin and VOUT pin is turned off to substantially reduce the current
consumption. The VOUT pin becomes the VSS level due to the internally divided resistance of several hundreds kΩ
between the VOUT pin and 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 state. 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 the ON/OFF pin is not used, connect it to the VSS pin if the logic
type is “A” and to the VIN pin if it is “B”.

„ Precautions
• Wiring patterns for the VIN, VOUT and GND pins should be designed so that the impedance is low. When mounting
an output capacitor between the VOUT and VSS pins (CL) and a capacitor for stabilizing the input between VIN and
VSS pins (CIN), the distance from the capacitors to these pins should be as short as possible.
• Note that the output voltage may increase when a series regulator is used at low load current (1.0 mA or less).
• Note that the output voltage may increase due to driver leakage when a series regulator is used at high
temperatures.
• Generally a series regulator may cause oscillation, depending on the selection of external parts. The following
conditions are recommended for this IC. However, be sure to perform sufficient evaluation under the actual usage
conditions for selection, including evaluation of temperature characteristics.
Input capacitor (CIN):
Output capacitor (CL):
Equivalent series resistance (ESR):
0.1 µF or more
0.1 µF or more
2.0 Ω or less
• The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitor is small
or an input capacitor is not connected.
• If the capacitance of the IC’s output block is small, the power supply fluctuation and load fluctuation characteristics
•
•
•
•
•
become worse. It is therefore important to sufficiently evaluate the output voltage fluctuation in the actual
equipment.
When the capacitance of the IC’s output block is small, if the power supply suddenly increases sharply, a
momentary overshoot may be output. It is therefore important to sufficiently evaluate the output voltage at power
application in the actual equipment.
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 6 in the
electrical characteristics and footnote *5) of the table.
