GENERAL DESCRIPTION

The NJM2828 is a negative output low dropout regulator.

Advanced bipolar technology achieves low noise, high precision

voltage and high ripple rejection.

Adjustable soft-start function is useful for reducing inrush current

and controlling power-on sequence. Moreover the discharge

function, the shunt SW, makes effective sequence control with the

soft-start function.

1.0 F Output capacitor and small package can make NJM2828

suitable for portable items.
