Overview
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 resistors connected to the PVCC, GND, and VREF pins.
The NCP/NCV51199 incorporates a high−speed differential amplifier to provide ultra−fast response to line and load transients.
Other features include source/sink current limiting, ...
