LDO Regulator, 450 mA, Ultra-High PSRR, Ultra-Low Noise

Favorite

Overview

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 µF input and a 1 µF output ceramic capacitor. It is available in two thickness ultra−small 0.35P, 0.65 mm x 0.65 mm Chip Scale Package (CSP), XDFN−4 0.65P, 1 mm x 1 mm and TSOP5 packages.
