NCP51145

DDR 1.8 Amp Source / Sink

V_TTTermination Regulator

The NCP51145 is a linear regulator designed to supply a regulated

termination voltage for DDR−II, DDR−III, LPDDR−III and

DDR−IV memory applications. The regulator is capable of actively

sourcing and sinking 1.8 A peak currents while regulating an output

voltage to within 20 mV. The output termination voltage is regulated

to the PV , GND, and V

pins.

REF

The NCP51145 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.
