The S-816 series consists of external transistor type positive voltage regulators, which have been developed using the CMOS process. These voltage regulators incorporate an overcurrent protection, and power-off function. A low drop-out type regulator with an output current ranging from several hundreds of mA to 1A can be configured with the PNP transistor driven by this IC.
Despite the features of the S-816, 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 regulators serve as ideal power supply units for portable devices when coupled with the SOT-23-5 minipackage, providing numerous outstanding features, including low current consumption. Since this series can accommodate an input voltage of up to 16V, it is also suitable when operating via an AC adapter.
