esta es el circuito es un regulador lm317

this is a reglated power supply you can build 2 one for +12 and other for +5 this can handle 15 amps

That is made for 220v mains operation (house power) so it isn't of any use in a car.

What part of Chile are you from? I just got back from a month in Vina del Mar. I love that country! Colo-colo! Superbien! Cachai? (My spanish sucks.)

Pablo Neruda is my hero.

yes but this circuit is easy to modifi only must jump the transformator ,rectifier , filters an conect directly to te car 12v you can regulate from 12v to 1.2 v perfectly

Please elaborate, tell me how.

Where in Chile are you? When I retire (in 40 or 50 years) I plan on living in La Serena in the winter and Pucon or Puerto Montt in the summer.

And as it's a linear regulator it will dissipate large amounts of heat.

For example, when regulating to 5v from 14 volts at 15amps, it will dissipate 135W as heat (supplying 75W to the load). Even when supplying 5A at 5V it will dissipate 45W as heat whilst only supplying 25W to the load.
