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.

Key Features

  • DDR1, DDR2, DDR3 and DDR4 Support.
  • 0.75VTT Generation.
  • ±20mV Output Voltage Offset.
  • 2 Amps Continuous Current Sourcing & Sinking.
  • 1.1V to 5.5V Wide Input Voltage Range.
  • Adjustable Output Voltage.
  • Suspend to RAM(STR), Enable & Soft Start Functions.
  • Stable with 22µF Ceramic Capacitor.
  • UVLO, Over Temperature and Over Current Protections.
  • Minimal External Components.
  • Pin/Function Compatible with SP299.
