XRP2997
2A DDRI/II/III/IV Bus Termination Regulator
August 2017
GENERAL DESCRIPTION
The XRP2997 is a Double Data Rate (DDR) termination voltage regulator supporting all power requirements of DDR I, II, III and IV memories and is capable of sinking or sourcing 2A continuously.
Tightly regulating its output voltage within ±20mV, the XRP2997 converts input voltages as low as 1.1V while the output voltage is adjustable through an external resistor divider or by forcing the VREF pin voltage. It maintains a fast line and load transient response and only requires an output capacitance of 22µF to operate. An enable function via an external MOSFET and a soft start feature allow for a controlled implementation of power-up sequencing.
