2A Sink/Source Bus Termination Regulator DESCRIPTION The EUP7171 is a high performance linear regulator designed to provide power for termination of a DDR memory bus. It significantly reduces parts count, board space and overall system cost over previous switching solutions. The EUP7171 contains a high-speed operational amplifier to provide excellent response to load transients. It also has an independent power source pin (VCNTL) for achieving better output driving capability. The www.DataSheet4U.com regulator can both sink and source up to 2A current. The output termination voltage can be tightly regulated to track 1/2 VDDQ by two external voltage divider resistors.
