In my current design I'm taking advantage of the over-current limit feature of a LM317 and using it as a fast acting short circuit protection device. This is a bad solution as the voltage drop across it is too big. I'm wondering if there are dedicated chips for this purpose? A simple two-pin device that cuts current flow if the current gets too big? I need it to act fast so a PTC or polyfuse is not going to work.
