GENERAL DESCRIPTION
The CM8561 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 1.6V
to 6.0V. The desired output voltage could be programmable
by two external voltage divider resistors.
The CM8561 is capable of sourcing or sinking up to 1.5A of
current while regulating an output VOUT voltage to within 2%
(DDR-I), 3% (DDR-II) or less.
The CM8561 provides low profile 8-pin SOIC package to save
system space.
