CM8563
1.5A LINEAR BUS TERMINATION REGULATOR
GENERAL DESCRIPTION
FEATURES
The CM8563 is a low cost linear regulator designed to provide
a desired output voltage or termination voltage for various
applications. The device contains a high-speed operational
amplifier to provide excellent response to load transients.
The CM8563 is capable of sourcing or sinking up to 1.5A, and
peaks up to 3A of current while regulating an output VOUT
voltage to meet the JEDEC SSTL-2 and SSTL-3
specification. .
Ideal for DDR-I and DDR-II
8-pin SOIC package
Source and sink up to 1.5A, no heat sink required
Integrated power MOSFETs
No external resistors required
Minimum external components
The CM8563 also incorporates a VFB pin to provide superior
load regulation and a VREF output as a reference for the
chipset and DDR DIMMS.
The CM8563 provides low profile 8-pin SOIC package to save
system space.
