NCP161AFCT330T2G IC REG LINEAR 3.3V 450MA 4WLCSP onsemi

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 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) and XDFN−4 0.65P, 1 mm x 1 mm.
