                  UR5513 Datasheet






                  The UR5513 is a sink/source tracking termination regulator. The

                  UR5513 possesses ahigh speed operating amplifier that provides

                  fast load transient response and only requires a minimum 30uF

                  ceramic output capacitor. The UR5513 supports remote sensing

                  functions and all features required to power the DDRIII and Low

                  Power DDRIII/DDRIV VTT bus termination. In addition , the UR5513

                  Provides an open-drain PGOOD signal to monitor the output

                  regulation and an EN signal that can be used to discharge VTT

                  during S3(suspent to RAM) for DDR applications.
