adjustment), Power-Good Function,
Discharge Function
The NR1600 series are CMOS-based low dropout
voltage regulator with Soft-start function and Power-
Good function.
An external capacitor (C
SS
) can be used to adjust the
Soft-start time during startup, making it easy to
suppress inrush current and adjust slew rate.
In addition, although it is a 500mA regulator with Soft-
start and Power-Good function, it has a lineup of
small packages of 1.2mm
x 1.2mm x 0.4mm, which
contributes to system space saving.
Power source for battery-p ower ed eq uip me nts ,
electrical home appliances and portable
communication equipments, etc.
