New Japan Radio NJM12884
NJM12884
LDO with Reverse Current Protection / Soft Start / Discharge Function
GENERAL DESCRIPTION
The NJM12884 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.
