HIGH OPERATING VOLTAGE
CMOS VOLTAGE REGULATOR
S-812C Series
The S-812C series is a family of high-voltage positive
regulators developed using CMOS technology. The
maximum operating voltage of 16V makes the S-812C
series best in high-voltage applications. Not only current
consumption is small but also power-off function is
included, the regulator is also suitable in constructing low-
power portable devices. Combination of power-off function
and short-current protection can be selected.
