VOLTAGE REGULATOR
S-812XXSG Series
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.
