Hey guys,
I'm building a LM350-based adjustable power supply with a PC PSU being used as the current source. Since I noticed that the PSU also has -5v and -12v rails respectively, I was wondering if i could feed the LM350 with +12v and -12v, effectively giving it "24v", which would give me a voltage of about 0v -> 22.5v in theory to play with, versus a 0v -> 10.5v with just 12v input.
Can anyone tell me if i will run into problems? The main issue I see now is that (if it works) the -12v rail supplies meagre amperage (less then 1) while the +12v is capable of 8A easily. Will this hurt me in the short/long run?
Thanks!
