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.
