Portable 3.3v regulator for a 9 volt battery?
I've seen a great deal of portable breadboard PSU's that output 5 volts from a 9 volt battery, and I find these fantastic! However, I was curious...is there any way to refine this futher down to get a steady 3.3 volts? I would like it to be something close to the system that sath02 has made here
as it not only better suites my nees, but makes sense to me.
Thanks in advance!
