Overview

NCP51199 は、DDR-2 および DDR-3 メモリ・アプリケーションに調整された VTT 終端電圧を供給するように設計されたリニア・レギュレータです。レギュレータは、出力電圧を +-10mV 以内に調整しながら、DDR-2 および DDR-3 用の +-2A のピーク電流を最大 +-1.5A までアクティブにソースおよびシンクできます。出力終端電圧は、PVCC、GND、VREF ピンに接続された 2 つの外部電圧ディバイダ抵抗によって、VDDQ2 を追跡するように調整されます。

  • SDRAM Termination Voltage for DDR2 / DDR3
  • Motherboard, Notebook, and VGA Card Memory Termination
  • Set Top Box, Digital TV, Printers

  • Supports DDR2 VTT Termination to 2 A, DDR3 to 1.5 A (peak
  • Supports DDR VTT Voltages as low as 600 mV at 1.2 A (peak)
  • Integrated Power MOSFETs
  • Stable with 10uF Ceramic Capacitance on VTT Output
  • High Accuracy VTT Output at FullLoad
  • Fast Transient Response
  • Builtin SoftStart
  • Shutdown for Standby or Suspend Mode
  • Integrated Thermal and CurrentLimit Protection
