The Murata OKI-78SR DC-DC power converters are a pair of drop-in replacements for the classic linear regulators, LM7803 and LM7805. Unit cost is about four bucks, where the LM78xx is more like $0.60, but they claim 95% efficiency and no need for a heat sink. Sounds like a nice tool to have in one’s parts box.
