We rather like the very-low-dropout L4931 from ST! This little guy will help you get your 4-20V battery or wall adapter down to a nice clean 3.3V with 2% regulation. Perfect for just about all electronics! This is a TO-92 package version, with up to 250mA current capability, and has internal current limiting + thermal shut-down protection which makes it sturdy and pretty much indestructible - at least electronics-wise (we're pretty sure a hammer might work...)
