Note1

regulators developed using CMOS technology.

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.

The S-812C series is a family of high-voltage positive
