NCP51190中文资料1.5 A DDR 端接稳压器数据手册ONSEMI规格书

描述 Description

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 Features

• 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
