Double voltage source
Circuit presentation
Double voltage source + 15V / -15V and + 5V / -5V stabilized
This circuit offers a set of two double voltages, at a maximum current of 1A. The 7815 and 7915 integrated circuits can be replaced with 7812 and 7912, or even 7809 and 7909, resulting in a different voltage output. 7805 and 7905 series integrated circuits are also used for positive and negative voltage.
For this type of circuit you should use a 2x 15V toroidal transformer at a current of 1-1.5A.
