NJM2827
Negative Output Low Drop Out voltage regulator
„ GENERAL DESCRIPTION
The NJM2827 is a negative output low dropout regulator.
Advanced bipolar technology achieves low noise, high precision
voltage and high ripple rejection.
It has soft-start and shunt SW function. 1.0µF Output capacitor
and small package can make NJM2827 suitable for portable items.
