The XRP2997 is a Double Data Rate (DDR) termination voltage regulator supporting all power requirements of DDR I, II and III 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.
Built-in source/sink overcurrent, over temperature and undervoltage lockout protections insure safe operation under abnormal operating conditions.
