Does anyone here have a suggestion for a 5v voltage regulator that accepts car voltage (13.9v-14.4v or so) with as little energy wasted as possible? Linears are out. I'm trying to power an atmega328 and very little else (a couple of transistors and a couple of small leds) from a car, and I'm trying…

Use tantalum caps instead of electrolytics and the MC34063A solution should be just what you need: cheap, efficient, long lasting. Tantalum caps are not as cheap as electrolytics, but you'll still come in under $13. -- The Ruggeduino : compatible with Arduino UNO, 24V operation, all I/O's fused and…

Thanks! I'll give that a shot, see how things run.

Try the LM2936 5.0V LDO regulator. It has a quiescent current of 15uA and up to 60V input.
