Im in the process of building a project variable power supply and was wondering is anyone could help me with the voltage regulator. I'm really wanting to use a linear power supply instead of a switching power supply, its just a personal preference, but Im stuck between the LM350 and the LM317. My transformer only puts out 20V/2A. The ready made power supplies I have seen similar to my application run an LM317 with a small heatsink in an enclosed box.
Where Im concerned is with the size of the heatsink that I will need to run either of these ICs. So I was hoping that someone would be able to help me out.
