NR1600 Series
500mA Low Dropout Voltage Regulator with Soft-Start Time Adjustment and Power-Good Function
-
Description
The NR1600 series are CMOS-based low dropout voltage regulator with Soft-start function and Power-Good function.
An external capacitor (CSS) 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 Softstart 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.
