Product specifications
2A DDRI/II/III/IV Bus Termination Regulator
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 V REF 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 under-voltage lockout protections insure safe operation under abnormal operating conditions.
The XRP2997 meets JEDEC SSTL-2, SSTL-18, HSTL, SCSI-1 and SCSI-3 specifications for DDR SDRAM memories.
The XRP2997 is offered in a RoHS compliant, “green”/halogen free 8-pin Exposed Pad SOIC package.
