NCP51145 Datasheet | onsemi

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...
