NCP161/D

NCP161

450 mA, Ultra-Low Noise

and High PSRR LDO

Regulator for RF and

Analog Circuits

The NCP161 is a linear regulator capable of supplying 450 mA

output current. Designed to meet the requirements of RF and analog

circuits, the NCP161 device provides low noise, high PSRR, low

quiescent current, and very good load/line transients. The device is

designed to work with a 1

mF input and a 1 mF output ceramic capacitor.

It is available in two thickness ultra−small 0.35P, 0.65 mm x 0.65 mm

Chip Scale Package (CSP) and XDFN−4 0.65P, 1 mm x 1 mm.
