Pin Number Pin Name Pin Function 1 VRO OUTPUT * Buffered Output of VRI Reference Input pin. 2 VCC INPUT * Regulator Analog Power Input pin. Connect to the system supply voltage. Bypass VCC to AGND with a 1 mF or greater ceramic capacitor. 3 AGND Analog Ground 4 VRI INPUT <.

NCP51510, NCV51510 3 Amp VTT Termination Source / Sink Regulator for DDR, DDR-2, DDR-3, DDR-4 The NCP51510 is a source/sink Double Data Rate (DDR) termination regulator specifically designed for low input voltage and low noise systems where space is a key consideration. The NCP51510 maintains a fast transient response and only requires a minimum VTT load capacitance of 10 mF for output stability. The NCP51510 supports remote sensing and all power requirements for DDR VTT bus termination.
