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.
