Overview
HIGH-PRECISION 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.
