CM8566 Datasheet, PDF (5/8 Pages) Champion Microelectronic Corp. – 2A ADJUSTABLE LINEAR REGULATOR

FUNCTIONAL DESCRIPTION
CM8566
2A ADJUSTABLE LINEAR REGULATOR
The CM8566 is a linear regulator that is capable of sinking
INPUTS
and sourcing 2A of current without an external heat sink.
The input voltage pins (VIN) determine the output voltages
(VOUT). At CM8566, the desired output voltage could be
The CM8566 integrates power MOSFETs that are capable of programmable by two external voltage divider resistors. VIN is
source and sink2A of current while maintaining excellent
suggested to connect to VDDQ of memory module for better
voltage regulation. The output voltage can be regulated within tracking with memory VDDQ.
3% or less by using the external feedback. Separate voltage
supply inputs have been added to fit applications with various
power supplies for the databus and power buses.
OTHER SUPPLY VOLTAGES
VCCA provide the voltage supply to the logic section and
OUTPUTS
internal error amplifiers of CM8566.
The output voltage pins (VOUT) are tied to the databus,
address, or clock lines via an external inductor. Output voltage
is determined by the VIN.
