NCV51190

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 load regulation, source/sink soft−start and on−chip thermal shut−down protection. The NCP/NCV51190 features the power−saving Suspend To Ram (STR) function which will tri−state the regulator output and lower the quiescent current drawn when the /SS pin is pulled low. The NCP/NCV51190 is available in a DFN8 package.
