NCP163AMX120TBG

NCP163AMX120TBG Description

The NCP163AMX120TBG from onsemi is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision power management in compact, power-sensitive applications. This fixed-output regulator delivers a stable 1.2V at up to 250mA with an ultra-low quiescent current of 20 µA, making it ideal for battery-operated and portable devices. Its 5.5V maximum input voltage and 91dB to 60dB PSRR (100Hz to 100kHz) ensure robust noise suppression, critical for sensitive analog and digital circuits. Packaged in a 4XDFN surface-mount form factor with Tape & Reel (TR) packaging, it suits automated assembly processes.

NCP163AMX120TBG Features

• High Efficiency: Ultra-low dropout and quiescent current (20 µA) extend battery life in portable applications.
• Exceptional Noise Immunity: 91dB PSRR at 100Hz minimizes output ripple, ideal for RF and precision analog systems.
• Robust Protection: Integrated over-current, over-temperature, and soft-start features enhance reliability.
