EXTERNAL TRANSISTOR TYPE
CMOS VOLTAGE REGULATOR

_02
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.

Remark 1.
To ensure you power cutoff of the external transistor when the device is powered down, the
EXT output is pulled up to V
IN
by a pull-up resistance (approx. 0.5 M) inside the IC.
2.
The diode inside the IC is a parasitic diode.
