One alternative is instead to parallel connect multiple three terminal regulators, with each regulator handling up to 1 Amp of current.

Voltage regulators such as the LM cannot just be connected in parallel without additional circuitry. An error occurred, please try again. The item you’ve selected was not added to your cart. om7812
