HIGH RIPPLE-REJECTION AND LOW DROPOUT
MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR
Rev.4.1
_00
The S-1132 Series is a positive voltage regulator with a low dropout voltage, high-accuracy output voltage, 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 overcurrent
protection circuit prevents the output 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.
