NCV51190 Datasheet (ON Semiconductor) - 1.5A DDR Memory Termination Regulator

NCV51190, 1.5A DDR Memory Termination Regulator

* NCP51190 Pin Number Pin Name Pin Function 1 PVCC The PVCC pin provides the rail voltage from where the VTT pin draws load current.

There is a limitation between VCC and PVCC.

The PVCC voltage must be less or equal to the VCC voltage to ensure the correct output voltage regulation.

NCP51190, NCV51190 1.5A DDR Memory Termination Regulator The NCP/NCV51190 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 re
