NCP51190 Datasheet | onsemi

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 regulated to track VTT = (VDDQ / 2) over the entire current range. The NCP/NCV51190 incorporates a high- speed differential amplifier to provide ultra- fast response to line and load transients. Other Features include extremely low initial offset voltage, excellent...
