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 1µF input and a 1µF 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.

Features

Ultra High PSRR 90dB at 1kHz, 20mA
Ultra Low Output Noise 10µVRMS
Very Low Dropout 80mV@250mA
Operating Input Voltage Range 1.9V to 5.5V
Ultra Low Quiescent current 18µA
Available in CSP4 0.35P package

Benefits

Excellent for power sensitive device like Wi-Fi module
Very well suited for noise sensitive application
Allow work with very low VIN-VOUT difference
Suitable for battery powered device
Improved efficiency during light load conditions
Great for space constrains application
