    hello friends,I have got a problem with making a Regulated power supply, that how to choose a heat sink for preventing the damage that might be occured. i have used LM317 IC for regulation.
    And, I want to use a short circuit protector circuit, which intimate us by glowing an LED whenever we short the load terminals.For this, i can use 555 IC, as it is working as a toggle flip-flop.But, I need a seperate Vcc for that. Is there any other method to do kile that....
    thank you.....,

    I have designed a 555 as a toggle flip flop, it may even be what you are referring to. We need a schematic of what you have to date to be able to help you though.
