    Hi all,
    I am using a 12v 100Ah battery. My load is taking 12v, 25A current. when i switch ON the load the voltage decrease to 11.2v .
    How to regulate the output voltage. please give me a circuit or guide me to design a circuit.

    thanks in advance

    I think it would be a very complex circuit. You will need a DC-to-DC converter and then regulate the output, using a switching regulator.

    On the other hand why do you need to keep it at 12V? Such drop is usually irrelevant for electronic circuits.
