Here's an idea I had for a switching regulator when I was bored.
This one doesn't boast excellent efficiency (LTSPICE says about 80% @150mA, with 9V in and 85% with 6V in) but it has a drop out voltage of 0.7V.
This is idea for powering 5V circuits with reasonable power drain (about 150mA) from a 9V battery or 3.3V circuits from four AA cells.
