NCP51510: ±3A Sink/Source DDR Termination Regulator

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 anda only requires a minimum VTT load capacitance of 10uF for output stability. The NCP51510 supports remote sensing and all power requirements for DDR VTT bus termination. The NCP51510 can also be used in low-power chipsets and graphics processor cores that require dynamically adjustable output voltages. The NCP51510 is available in the thermally-efficient DFN10 Exposed Pad Package, and is rated both Green and Pb-Free.
