概览

NCP51199 是一款线性稳压器，适用于为 DDR-2 和 DDR-3 内存应用提供调节后 VTT 端接电压。该稳压器对于 DDR-2 能够有效源/汲最高 +-2A 的电流，对于 DDR-3 能够有效源/汲最高 +-1.5A 的电流，同时能够将 VTT 输出电压调节在 +-10 mV 范围内。输出端接电压调节为由两个联接到 PVCC、GND 和 VREF 引脚的外部分压电阻跟踪 VDDQ2。

  • 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
