External Transistor Type Voltage Regulators
S-816 Series
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.

Note: To ensure you power cutoff of the external transistor when the device is powered down, the EXT output is pulled up to VIN
by a pull-up resistance (approx. 0.5M
W
) inside the IC.
The diode inside the IC is a parasitic diode.
