5.5 V INPUT, 300 mA VOLTAGE REGULATOR
Rev.2.3_00
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 μF small ceramic capacitor can be used. It operates with low current consumption of 45 μA 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.
