Review of a small motor controller schematic.

Austin,
The difference in capacitor values stems from Tantalums being very close to labeled value and electrolytics being a little less precise and varying over their life. I like to use the bigger caps if I have room. I also cannot use tants for audio so it makes less different parts to buy for my work. The other thing is tants tend to short when they go bad or lightning happens. On a power supply that can be catastrophic. If you find that regulator oscillates, you may have to add a .01-.1 cap in parallel with the output cap near the regulator.
