NCP51198, NCV51198
1.5A DDR Memory
Termination Regulator
The NCP/NCV51198 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/NCV51198 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/NCV51198 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/NCV51198 is available in a SOIC−8 Exposed Pad
package.
