CM8562P
2A SINK & SOURCE ADJUSTABLE LINEAR REGULATOR
GENERAL DESCRIPTION FEATURES
The CM8562P is a low cost linear regulator designed to Ideal for DDR-lDDR-ll and DDR-lll
provide a desired output voltage or termination voltage for
8-pin SOIC w/ power pad package
various applications by converting voltage supplies ranging
Source and sink up to 2A , no heat sink required
from 1V to 6.0V. The desired output voltage could be
Integrated power MOSFETs
programmable by two external voltage divider resistors.
Programmable output voltage by external resistors
Output voltage could go down to 0.6V
The CM8562P is capable of sourcing or sinking up to 2A of
Iccq at VCCA less than 500uA
current while regulating an output VOUT voltage to within
Current limit protection and Short Circuit protection
2%(DDR-I) , 3% (DDR-ll) or less .
Thermal shutdown protection
Shutdown for standby or suspend mode operation
The CM8562P provides low profile 8-pin SOIC package to
Minimum external components
save system space.
