Mouser – DDR bus termination voltage regulator can sink or source 2A continuously (XRP2997IDBTR-F)

The Exar XRP2997 double data rate (DDR) 2A bus termination voltage regulator is now available from Mouser. It supports all power requirements of DDR I, II and III memories and is capable of sinking or sourcing 2A continuously.

By tightly regulating its output voltage within ±20mV, the XRP2997 2A bus termination regulator 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. A built-in source / sink over-current, over-temperature and under-voltage lockout protections on the XRP2997 ensures safe operation under abnormal operating conditions.

Typical applications include DDR I/II/III memory termination, active Termination buses, audio / video equipment and video / graphics cards.
