The NCP51145 is a linear regulator designed to supply a regulated VTT 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 track VDDQ / 2 by two external voltage divider resistors connectedto the PVCC, GND, and VREF pins.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.
