NCP51190, NCV51190

1.5A DDR Memory

Termination Regulator

The NCP/NCV51190 is a simple, cost−effective, high−speed linear

regulator designed to generate the V 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 V

/ 2) over the entire current range.

DDQ

DFN8

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.
