Overview

Description

The RAA214035 is an ultra-low noise, high PSRR, low dropout regulator capable of sourcing up to 3A of load current with only 180mV dropout voltage. It operates from an input voltage of 1.1V for very low voltage applications to 6.5V. The RAA214035 has an ultra-low output noise and high PSRR without a feed-forward capacitor. It only requires a single 1µF noise-reduction capacitor to achieve 7µVRMS output noise, making it great for noise-sensitive and space-constrained applications.
