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