  • I use this with a AAA battery as a small stand-alone audio amplifier for an earpiece. The efficiency is unbelievable. To get the unit to 3.3V I use the following booster:

    This little booster is super efficient as well. Bottom line is that this combination, even with such a small battery, seems to have as much run time as with a 9V battery would using an LM386.

No public wish lists :(
