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
