I want to adapt this voltage regulator to work with two 9V batteries and use less electronics components. My first idea was to use a lm317 and a lm337 but it need 1.5V of headroom to work, and a lm7807 need 2 volts. the actual design only need 0.6V to work. Another issue of this design is that if one battery is low the output voltage of the other leg is balanced to have the same absolute value. funny isn´t? :shock:
Probably the best idea is to use a zenerd as voltage regulator.
some one have any ideas? :?
