Very Low Output Negative Voltage Regulator

GENERAL DESCRIPTION

PACKAGE OUTLINE

The NJM2829 is a negative voltage regulator that delivers up

to 100mA output current with the output voltage of -0.8 to -1.3V

with ON/OFF control.

Advanced Bipolar technology achieves low noise, high ripple rejection,

and high precision voltage.

It has soft-start and shunt SW function. 2.2

µF Output capacitor

and small package can make NJM2829 suitable for portable

items
