Hi Everyone,
I want to make a 12 car battery charger circuit. I want to use an IC regulator for it.
I want to get opinion about which IC will be better? LM2576(switching regulator) or LM138 a linear regulator?
Input voltage is 18v(transformer) and current requirement is upto 3 Amps.
Actually, linear regulators heat quickly and a large heat sink will be required for 3 amps. Probably, a fan also.
what is your opinion?
thanks
