As we all know linear regulators cannot handle a lot of amperage and tend to waste a lot of energy, so I was thinking if it is possible to create a regulated output then put the amperage after the regulation...

A slight demonstration of a schematic to show what I mean:



Is this possible? If yes is there a schematic I can look at? What should I look for?

sorry for the bad picture, I tried to make it better but failed..

--Edit--
I'm not trying get my circuit to work, just to convey the meaning.. I know this circuit won't work the way I want it, it is just an illustration.


Question: Imgur is misbehaving!
Answer: I am unable to reproduce this issue at this time. I've seen imgur have issues in the past (both with Stack account and anonymous hosting) so my best guess is that on May 31 imgur had some performance or routing issues. I did some Googling and found some anecdotal evidence to indicate that the issue was widespread on May 31, though nothing concrete. Bottom line is it's working now.
