EXTERNAL TRANSISTOR TYPE CMOS VOLTAGE REGULATOR

The S-816 Series, developed using the CMOS technology, is an external transistor type positive voltage regulator which incorporates an overcurrent protection circuit and an ON/OFF circuit. A low drop-out type regulator with an output current ranging from several hundreds of mA to 1 A can be configured with the PNP transistor driven by this IC.
Despite the features of the S-816 Series, which is low current consumption, the improvement in its transient response characteristics of the IC with a newly deviced phase compensation circuit made it possible to employ the products of the S-816 Series even in applications where heavy input variation or load variation is experienced.
The S-816 Series regulator serves as an ideal power supply unit for portable devices when coupled with the small SOT-23-5 package, providing numerous outstanding features, including low current consumption. Since the S-816 Series can accommodate an input voltage of up to 16 V, it is also suitable when operating via an AC adapter.
