NCP51190: 1.5 Amps DDR Termination Regulators

The NCP51190 is a simple, cost-effective, high-speed linear regulator designed to generate the VTT termination voltage rail for DDR-I, DDR-II and DDR-III memory. The regulator is capable of actively sourcing or sinking up to +-1.5 A for DDR-I, or up to +-0.5 A for DDR-II, -III while regulating the output voltage to within +-30 mV.

特性
  • Generate DDR Memory Termination Voltage (VTT)
  • For DDRI, DDRII, DDRIII Source / Sink Currents
  • Supports DDRI to 1.5 A, DDRII to 0.5 A (peak)
  • Integrated Power MOSFETs with Thermal Protection
  • Stable with 10UF Ceramic VTT Capacitor
  • High Accuracy Output Voltage at FullLoad
  • Minimal External Component Count
  • Shutdown for Standby or Suspend to RAM (STR) mode
  • Builtin Soft Start
