Dual Polarity Power Supply


Posted on Feb 5, 2014

This dual polarity power supply is easy to build, requires few parts, and is adjustable from 0-15 volts. It is great for powering op amp circuits, as well as other circuits that require a dual supply voltage. 4. U1 and U2 can only go down to a minimum of +-1. 2V. If you need to go lower, you can add two 1N4003 diodes in series with the output of th

e regulator. The diodes drop about 0. 6V each, which will allow the supply to go to 0. Note that this will also decrease your maximum output voltage by 1. 2V. (Thanks to Steve Horvath, horvaths@techcomnet. com for the suggestion).
