The S-812XXSG Series is a three-terminal positive voltage regulator
made using the CMOS process. Since the S-812XXSG Series has
higher precision output voltage and consumes less current than existing
three-terminal voltage regulators, battery-powered portable equipment
can have a higher performance and a longer service life.
Applications
Constant voltage power supply of battery-powered equipment, communications equipment, video equipment
and others
