Overview
The NCP167AMX330TBG is a linear low dropout (LDO) regulator produced by onsemi, designed to meet the stringent requirements of RF and analog circuits. This device is capable of supplying up to 700 mA of output current and is characterized by its ultra-low noise, high power supply rejection ratio (PSRR), low quiescent current, and excellent load/line transients. It operates with a 1 µF input and a 1 µF output ceramic capacitor and is available in ultra-small packages, including the 0.35P, 0.65 mm x 0.65 mm Chip Scale Package (CSP) and the XDFN-4 0.65P, 1 mm x 1 mm package.
