Rev.1.0_00 SUPER-LOW OUTPUT LOW DROPOUT S-11L10 Series CMOS VOLTAGE REGULATOR 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 realiz
