Overview
The NCP103AMX300TCG is a 150 mA Low Dropout (LDO) linear regulator produced by onsemi. This device is designed to provide a very stable, accurate voltage with low noise, making it suitable for space-constrained, noise-sensitive applications. It is particularly optimized for battery-operated portable applications through its dynamic quiescent current adjustment, which ensures very low IQ consumption at no-load conditions.
