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.

Protective features include soft−start, source/sink current limits

and thermal shutdown. Open−drain VTT OK output (POK) is added

for system monitoring. The shutdown pin can tri−state the regulator

output for Suspend To RAM (STR) state. This device is available in a

SOIC−8 package.
