12V to 7+ volt voltage regulator parts

Recommended Posts

Howdy all,

I'm trying to fit a voltage step down in a small space. Going from 12 to 7 Volts with no change to amps. I've pulled apart one of those cheap cigarette adapters and was able to achieve what I need but now I need to go smaller. I think I’ve identified the parts on the adapter that I need now I just need to find out what they are and where to get them to build a small board. Any suggestions would be greatly appreciated.

Thanks

Use a LM317T with 0.1uf and 1uf capacitors. You can use a 260 Ohm resistor and a 4K7 variable. Connect a voltmeter to the output and a 12V input, use the pot on the variable resistor to change output value until you get 7V. You can find the schematic on the net anywhere.

Hope this helps. :D
