ETA钰泰 ETA5050 500mA低压差线性稳压器IC

　　DESCRIPTION

　　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.
