Description:

Termination regulator.

NCV51199, Termination Regulator

Pin No.

Pin Name Description 1 PVCC Input voltage which supplies current to the output pin.

CIN = 470 mF with low ESR.

2 GND Common Ground 3 VREF Buffered reference voltage input equal to ½ of VDDQ and active low shutdown pin.

An external resistor divider dividing down the PVCC voltage

NCP51199, NCV51199 DDR 2-Amp Source / Sink VTT Termination Regulator The NCP/NCV51199 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 ±2 A peak currents for DDR 2, and DDR 3 up to ±1.5 A while regulating the VTT output voltage to within ±10 mV.

The output termination voltage is regulated to track VDDQ / 2 by two external voltage divider
