NJM12877
LDO with Reverse Current Protection / Soft Start / Discharge Function
GENERAL DESCRIPTION
The NJM12877 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.
