Super-Low Output Low Dropout CMOS Voltage Regulator S-11L10 Series



S-11L10 Series, developed using the CMOS technology, is a positive voltage regulator IC which has the low output voltage, the high-accuracy output voltage and the low current consumption (150 mA output current).

A 1.0 µF small ceramic capacitor can be used. It operates with low current consumption of 9 µA typ.

The overcurrent protection circuit prevents the load current from exceeding the capacitance of output transistor. The power-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-23-5 and SNT-6A(H) packages realize high-density mounting.

Features

o Low output voltage: 0.8 V to 3.3 V, selectable in 0.05 V step.
