Hello. I got a little problem here. You see, I need to control two dc motors. Each one consumes .7 A so I had a variable reguator for each of them. I used the LM317 and it is supposed to give 1.5 A, but when I used them, after a while the motors stop and the variable regulator are so hot I can´t even touch them... Does anybody can give me any other idea of how to get 4 V for the motors?? My power source is a battery (11.7V, 10A). I need this motors working because they "are" the wheels of a vehicle we´re building.

Thaks a lot to all.
