600mA辍学率调节器--AT805

一 概述

The AT805 is a high performance positive voltage regulator designed for use in applications requiring very low input voltage and very low dropout voltage at 600mA amps. It operates with a VIN as low as 1.8V, with output voltage programmable as low as 0.8V. The AT805 features ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, the AT805 has an enable pin to further reduce power dissipation while shut down. The enable pin may be tied to VIN if it is not required for ON/OFF control. The AT805 provides excellent regulation over variations in line, load and temperature.
