NCP51199:DDR 2Amp Source / Sink VTT Termination Regulator

The NCP51199 is a linear regulator designed to supply a regulated VTT termination voltage for DDR-2 and DDR-3 memory applications.The regulator is capable of actively sourcing and sinking +-2A peak currents for DDR-2 and DDR-3 up to +-1.5A while regulating the VTT output voltage to within +-10mV.The output termination voltage is regulated to track VDDQ2 by two external voltage divider resistors connected to the PVCC,GND,and VREF pins.

技术特性
  • Supports DDR−2 VTT Termination to ±2 A, DDR−3 to ±1.5 A (peak)
