Hello guys. I am using LM338 regulator for my project. But when I build the circuit, the output voltage is equal to the input(I tried it on breadboard). There is no short circuit in the LM338 legs. The voltage is collected directly on R1 and the resistor gets very hot. There is no heating in...
I have a 52V transformer that after rect. produces 3.3A at 52V. I wish to use either a LM317 or a LM338 with 2N3055 power transistors.
If you run 2N3055's in parallel you are suppose d to have a resistor like a 0.1Ohm 10W from each emitter so that thermal runaway doesn't take place.Surely the...
