Circuit Project Electronic

This circuit is my variation on Charles’ floating 9V supply.  My design uses feedback regulation instead of a zener shunt regulator to stabilize the output against battery voltage and load variations.  Replacing the shunt regulator with feedback control makes the supply more efficient for output loads of less than about 500ua.  That might be important if the 9V battery must supply maximum current or needs longer operational life.
