Overview
The NCP103AMX285TCG is a high-performance, low dropout linear regulator (LDO) produced by onsemi. This 150 mA LDO is designed to provide a stable, accurate voltage with low noise, making it suitable for space-constrained and noise-sensitive applications. It is particularly optimized for battery-operated portable devices, featuring dynamic quiescent current adjustment to minimize power consumption at no-load conditions.
