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.
