Introduction

ETA5050 is a 500mA low noise and fast transient response liner regulator with adjustable output voltage and ultra- low dropout voltage. Its output voltage is programmed by a resistor divider, and can be as low as 0.8V, which satisfies the most advanced ICs which may require supply voltage to be 0.9V - 1.2V. ETA5050 is consists of a precise voltage reference, an error amplifier, a compensation network and a low ON- resistance power P- MOSFET. It also integrates many protection circuitry, like current limit and over- temperature protection module. ETA5050 is in a tiny SOT23- 5 package.
