I'm finishing up a simple 2-30v, 15A linear adjustable power supply (LM723).
I am concerned about back-emf killing my circuit when I test motors, solenoids,
coils, etc. In addition to the LT10A04 shown in the schematic, I installed a 1N4007
across each power transistor. I subbed a BD139 for the BD243C, and used four TIP3055
for the output transistors. Other than that, everything else is same.
Do I need anything more at the final output? I'm thinking a large Shockley on the positive terminal as the ultimate emf
protection...
I am reassembling my test layout into an enclosure and I don't want the smoke
to get out after all my work.
Note, I omitted the mistake where the input is directly
shorted to the output. I think the author goofed up. Otherwise, it seemed to kick butt
nicely on the benchtop.
