NJM2829 Datasheet, PDF (1/9 Pages) New Japan Radio – Very Low Output Negative Voltage Regulator

NJM2829
Very Low Output Negative Voltage Regulator
GENERAL DESCRIPTION
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. 2.2µF Output capacitor
and small package can make NJM2829 suitable for portable
items
