CM8562B
1.8A SINK & SOURCE ADJUSTABLE LINEAR REGULATOR
GENERAL DESCRIPTION
FEATURES
The CM8562B is a low cost linear regulator designed to
provide a desired output voltage or termination voltage for
various applications by converting voltage supplies ranging
from 1V to 6.0V. The desired output voltage could be
programmable by two external voltage divider resistors.
The CM8562B is capable of sourcing or sinking up to 1.8A
of current while regulating an output VOUT voltage to within
2%(DDR-I) , 3% (DDR-ll) or less .
The CM8562B provides low profile 8-pin SOIC package to
save system space.
