NCP5208 DDR I/II Termination Regulator The NCP5208 is a linear regulator specifically designed for the active termination of DDR I/II SDRAM.

The device can be operated from a single supply voltage as low as 1.7 V.

For DDR I applications, the device is capable of sourcing and sinking current up to 1.5 A with the output voltage regulated to within "3% or better.

A separate voltage feedback pin ensures superior load regulation against load and line changes.
