NCP51145 Datasheet Termination Regulator

Manufacturer: onsemi

Overview: 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.
