NCP161ASN330T1G

NCP161ASN330T1G is an ultra-low noise and high PSRR, LDO regulator for RF and analogue circuits. It is a linear regulator capable of supplying 450mA output current. Designed to meet the requirements of RF and analogue circuits, this 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. Typical applications include battery-powered equipment, wireless LAN devices, smartphones, tablets, cameras, DVRs, STBs, and camcorders.
