ADP151WAUJZ-1.8-R7 | 1.8 V Low Noise LDO Regulator | High PSRR Linear IC

Product Overview

     ADP151WAUJZ-1.8-R7 is a low noise, low dropout (LDO) linear regulator that provides a fixed 1.8 V output with excellent power-supply rejection ratio (PSRR) and ultra-low output noise. Designed for noise-sensitive analog, RF, and mixed-signal systems, it ensures clean and stable power for ADCs, DACs, RF transceivers, and low-power digital ICs. Its low quiescent current and small package make it ideal for space-constrained and battery-powered designs.
