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.

S-1132 Series
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 on-
resistance 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.

Line
regulation
∆V OUT1
∆VIN •VOUT
Indicates the dependency of the output voltage on the input voltage. That is, the values show how much the output
voltage changes due to a change in the input voltage with the output current remaining unchanged.

5. Load regulation (∆VOUT2)
Indicates the dependency of the output voltaDgeatoanSthheeotu4tUpu.ct ocmurrent. 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).
Vdrop = VIN1 − (VOUT3 × 0.98)
