I have finished putting together a variable power supply using this design **broken link removed**
I found the initial design here. On that web page it says that this design has capabilities of up to 30V at 1.5A. But now that I have it built I realized that it's nearly impossible, at any voltage at 0.5A, dissipate enough heat with any heat sync.
I'm not quite sure what the person who wrote the original article (at the link above) was smoking, but they insist to "Be sure to put a cooling rib on IC1, at it's max 1.5 A current it quickly becomes very hot..." and a simple "cooling rib" will defiantly not solve the problem of the regulator becoming hot.
So, I want an output of 30v at at least 1A. Is there any modifications I can make (like get a different regulator) or will I just have to limit the output current?
