circuit dc 12 v to 3.7 v
Hai shahidsiddiq8
You may ise the given circuit which uses only one LM317 and is capable of varying between any voltage from 1.2v to 27 volts when fed with 30 volts DC and up to 1.5 Ampheres as per its datasheet says. In my practical experiences, i have used the same circuit to draw up to 1 Ampheres. But do use a good heat sink. In your case feed 12 volts and adjust the 2K variable resistor to get the desires voltage at the output. Hope it helps you.
