HIGH RIPPLE-REJECTION LOW DROPOUT
MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR
Rev.2.2
_02
The S-1135 Series, developed using the CMOS technology, is a positive voltage regulator IC which has the low dropout
voltage, the high-accuracy output voltage and the low current consumption (300 mA output current).
A 1.0
F
small ceramic capacitor can be used. It operates with low current consumption of 45
A
typ.
The overcurrent protection circuit prevents the load current from exceeding the current capacity of the output transistor. The
ON / OFF circuit ensures longer battery life.
Various capacitors, also small ceramic capacitors, can be used for this IC more than for the conventional regulator ICs which
have CMOS technology.
Furthermore, a small SOT-89-5, SOT-23-5, and HSNT-6A packages realize high-density mounting.
