I am building a MIDI player using Arduino platform since I got Arduino Duemilanove in late 2009. A year later, I came up with a working (but not perfect) version. This year I tried to build a breadboard version. The next target ? Of course a standalone portable version on PCB. The problem is, how to power up my little gadget with batteries like CR2032.
After searching the web and I finally decided to use MCP1700 from MicroChip. It is a LDO voltage regulator in TO-92 package.

I have bought a few of them for my battery-powered projects.
