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 16 V makes the S-812C
series best in high-voltage applications. Not only
current consumption is small but also shutdown
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.
