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.

MARKING  
DIAGRAM  
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  
SO−8 package.
