 		 #155466 - Did you test the LM2674 actually?
Responding to: ???'s previous message
Richard said:
Neither the line or load regulation seems to be particularly good, and since the O/P is concerned about line regulation, it might not be a particularly good choice for him.

Line and load regulation of the LM2674 are excellent. Pretty well for a digital 5V supply. By the way, I always add a pi-filter at output to further suppress the ripple.
