i tried to connect 7812 to laptop charger 19V 3.5A. and the wire start to smoke. 3.5A is too much for the regulator?
how to limit it? it is not possible to put resistor in series becoz we need so much wattage.
what alternate things i can do.
i have checked the pinouts in datasheet. so i connected them correct.
do so much current passes through regulator even though no load is connected?
