HIGH RIPPLE-REJECTION LOW DROPOUT
MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR
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
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.
