NCP51198 - 1.5A DDR Memory Termination Regulator

* NCP51198 Pin Number SO8 *EP Pin Name Pin Function 1 GND Common Ground.

2 /SS Suspend Shutdown supports Suspend To RAM function.

CMOS compatible input sets VTT output to high impedance state.

Logic HI = Enable, Logic LO = Shutdown.

3 VTTS VTTS is the VTT sense input.

1.5A DDR Memory Termination Regulator NCP51198, NCV51198 The NCP/NCV51198 is a simple, cost effective, high speed linear regulator designed to generate the VTT termination voltage rail for DDR I, DDR II and DDR III memory.

The regulator is capable of actively sourcing or sinking up to ±1.5 A for DDR I, or up to ±0.5 A for DDR II / III while regulating the output voltage to within ±30 mV.

The output termination voltage is tightly reg
