Overview
The NCP160AMX280TBG, produced by onsemi, is a high-performance linear voltage regulator designed to meet the stringent requirements of RF and analog circuits. This device is capable of supplying up to 250 mA of output current and is distinguished by its ultra-low noise and high Power Supply Rejection Ratio (PSRR). The NCP160 is available in ultra-small packages, including the Chip Scale Package (CSP) and XDFN-4, making it ideal for space-constrained applications.
