Hi all. I'm working on a little circuit that will live in my car...so I need an automotive voltage regulator. Cost isn't really a huge concern since I only need a couple. I know many people like the LM2940 though I recall a post about the capacitors it needs being expensive. What I'm unclear on is whether that was for no load regulation or if the low ESR caps are always needed. I'm not so great on power supply design so any help would be awesome! Thanks!
