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 lo...
