NCP51145
DDR 1.
8 Amp Source / Sink VTT Termination
Regulator
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 connected to 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 ...
