Datasheet Summary
Ultra Low Noise, High PSRR, LDO
The RAA214020 is an ultra-low noise, high-PSRR, low-dropout voltage regulator. The LDO operates from an input voltage range of 2.7V to 5.5V and can source a maximum 2A load. The output is adjustable with external feedback resistors anywhere from 0.9V up to 5.5V-VDROPOUT.
The RAA214020 has a low output noise of 6.3µVRMS typical and high PSRR which makes it well-suited for post-regulation in low-noise applications.
The operating quiescent current is typically 195µA and drops to a couple nanoamps typical at room temperature when in shutdown making it great for portable applications.
