4MHz Monolithic Synchronous Step-Down Regulators Bring High Efficiency to Space-Sensitive Applications - DN304 Design Notes__ Linear Technology/Analog Devices
5 Volt Regulator - Scroll for this one - You need to add a 5 volt regulator to power a USB device and this regulator needs to be a low-dropout type that consumes "micro" power so that it doesn't discharge the battery on its own. There are commercial regulators like the TPS76750Q in the PWP package that will do the job with just a couple of good ceramic bypass capacitors. (There are a bewildering number of suitable regulator choices.) But if you like to build your gadget from parts on hand, below are a couple of circuits that will work. __ Contact: Charles Wenzel of Wenzel Associates, Inc.
