DESCRIPTION
SCI78100Y Series is a fixed type positive voltage regu-
lator developed by using the CMOS silicon gate process
and is composed of a low current consumption refer-
ence voltage circuit, a differential amplifier, an output
control transistor and a voltage setting resistor.
The output voltage is fixed inside the IC, and various
standard voltage parts are available.
The package is a SOT89-3pin plastic package.
