hello,

I wanted to know if by using two lm350 in parallel, I would be able to
use 2 * 3amp ?
One of them usually regulated a max of 3 amp.
I also, I heard i could add a transistor in parallel to one LM, where
would be the base and collector hooked to , assuming (NPN) the emitter
is at the output.
thanks

ken

** Forget paralleling - go buy an LM338K, it does up to 6 amp.

** Bad idea.
