SUPER-LOW OUTPUT VOLTAGE LOW DROPOUT
CMOS VOLTAGE REGULATOR
Rev.2.2_00
The S-11L10 Series, developed by using the CMOS technology, is a positive voltage regulator IC which has low output
voltage, high-accuracy output voltage and 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 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, small SOT-23-5 and SNT-6A(H) packages realize high-density mounting.
