NCV51190MNTAG

The NCP/NCV51199 is a linear regulator designed to supply a regulated VTT termination voltage for DDR−2 and DDR−3 memory applications. The regulator is capable of actively sourcing and sinking �2 A peak currents for DDR−2, and DDR−3 up to �1.5 A while regulating the VTT output voltage to within �10 mV. The output termination voltage is regulated to track VDDQ / 2 by two external voltage divider resistors connected to the PVCC, GND, and VREF pins. The NCP/NCV51199 incorporates a high−speed differential amplifier to provide ultra−fast response to line and load transients. Other features include source/sink current limiting, soft−start and on−chip thermal shutdown protection.
