Product Introduction

A high performance, 500 mA LDO regulator, with high PSRR and very low noise, with low ground current.

Ideal for battery-operated applications, features 1% accuracy, very low dropout voltage (typically 200 mV @ 500 mA), and low ground current at light load (typically 90 μA). Equipped with a logic-compatible enable pin, can be set into a zero-off-mode current state, typically drawing only 0.5 μA current when disabled.

A μCap design operating with very small ceramic output capacitors for stability, thereby reducing required board space and component cost.

Available in fixed-output voltages and adjustable output versions in the compact 2 mm x 2 mm TDFN lead-less package or the thin SOT23-5 package.
