Standard Regulator Neg/Pos -0.3V to 6V 2A 8-Pin SOIC T/R

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.

• 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
