The NCP/NCV51200 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 NCP/NCV51200 maintains a fast transient response and only

requires a minimum output capacitance of 20 F. The NCP/NCV51200

supports a remote sensing function and all power requirements for

DDR VTT bus termination. The NCP/NCV51200 can also be used in

low?power chipsets and graphics processor cores that require

dynamically adjustable output voltages.

The NCP/NCV51200 is available in the thermally?efficient DFN10

Exposed Pad wettable flank package, and is rated both Green and Pb?free.
