Quick question - what do you think the heat capacity of a LM317 might be? The use case is that I want to ignite e-matches, which requires are short duration high current and would prefer to just use bunch of linear regulators without a heatsink. But I have no idea what the thermal capacity of a LM317 might be, and I don't want to kill the regulators!
I think I would need something like 10-15W of heat dissipation for maybe 100ms.
