Product Overview NCP161: 450 mA, Ultra-Low Noise and High PSRR LDO Regulator for RF and Analog Circuits For complete documentation, see the data sheet Product Description 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.
