NCP51199, NCV51199

DDR 2-Amp Source / Sink

V_TTTermination Regulator

The NCP/NCV51199 is a linear regulator designed to supply a

regulated V 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

voltage divider resistors connected to the PV , GND, and V

pins.

REF

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, soft−start and

on−chip thermal shutdown protection.
