I would like to build an add-on project box to use with an existing fixed 12vdc power supply (20A, 13.8vdc, Regulated) that I already own and is intended for use with a ham transmitter.
What I have in mind is a bench tester / battery eliminator that would allow me to produce 1.2vdc to 12vdc , at least. ... Since what I have is fairly substantial, I'd like to built it to 5A. potential, although most of its use will be at 1.5A or less.
I've Googled & found some information & some confusion to me ... (I'm just a hobbyist & it's been ~ 40 years since I built a few Heathkits ).
The LM338 looks good to me, but then I read a mention of the LM338K and the LM338T ... So o o o, your experience can save me a lot of trouble and frustration and head me in the right direction. Thanks for your patience, Tom.
