Overview
The NCP177AMX120TCG is a high-performance, low dropout linear voltage regulator (LDO) from onsemi. This CMOS LDO is designed to deliver excellent noise and dynamic performance, making it an ideal choice for powering precision and noise-sensitive circuitry in portable applications. The device features an adaptive ground current behavior, consuming only 60 μA of quiescent current under no-load conditions. It also includes an enable pin for ON/OFF control of the output voltage and offers active discharge functionality in the NCP177A version.
