EUP7171

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 regulator can both sink and source up to 2A current. The output termination voltage can be tightly regulated to track 1/2 V_DDQ by two external voltage divider resistors.

The EUP7171, used in conjunction with series termination resistors, provides an excellent voltage source for active termination schemes of high speed transmission lines as those seen in high speed memory buses. A typical DDR memory system is seen in Datasheet
