Designed to meet the requirements of RF and analog circuits, the NCP163 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 0.35 P, 0.65 mm x 0.65 mm chip scale package (CSP) and XDFN4 0.65 P, 1 mm x 1 mm.
