AMC7638

DESCRIPTION

FEATURES

The AMC7638 series is a low dropout regulator

rated for 450mA output current. Low power

consumption and high accuracy is achieved through

CMOS technology and internal trimmed reference

voltage.

The AMC7638 series consists of a high-precision

voltage reference, error correction circuit, and a current

limit output driver. The fast transient response is an

outstanding feature for applications with various loads

2% internally trimmed output

Input-Output differential of typ. 360mV at 300mA

& low quiescent current of 10

µA in typical

Short circuit protection

Internal thermal overload protection

Enhanced pin-to-pin compatible to the XC62FP

series, RT9261/A.

3-Lead SOT-89 and SOT-223 packages.

Lead (Pb) free process
