NE57811S - Philipss

NE57811S Advanced DDR memory termination power with shutdown

The NE57811 is designed to provide power for termination of a Double Data Rate (DDR) SDRAM memory bus. It significantly reduces parts count, board space, and overall system cost compared to previous solutions. The NE57811 DDR termination regulator maintains an output voltage (DDR reference bus voltage) that is one-half that of the RAM supply voltage. It is c.
