I am creating a regulated 3.4 Volts 5 Amp DC supply from 24 volts 5Amp DC supply, now the problem is that when I use a load of 2 amp the transistors start heating up and then burnt out even I m using heat sinks, due to heavy power dissipation on transistor.I m attaching a schematic of my regulator supply,kindly check it and help me out.I have to dirve a load about 5 amp.
