GENERAL DESCRIPTION

The NJM12856 is a low dropout regulator which achieves

high ripple rejection, low noise and high speed response with

the bipolar technology.

Adjustable soft-start function is useful for reducing inrush

current and controlling power-on sequence. Moreover the

discharge function makes effective sequence control with the

soft-start function.

In addition, the reverse current protection makes external

SBD unnecessary.
