NE57814 - Philipss

NE57814 DDR memory termination regulator with standby mode and enhanced efficiency

The NE57814 is designed to provide power for termination of a DDR memory bus. It significantly reduces parts count, board space, and overall system cost over previous switching solutions. The NE57814 has an independent power source pin (VD) for further reducing the operational power and a standby low-power mode for energy-sensitive portable applications. The.
