This Dual supply circuit is suitable for installation of power analog (audio or measurement), it provides a bipolar voltage with voltage source between 20 and 50 V (in audio power amp, for example). Regulated output voltage is 15V, but can be adjusted from + /-12V or + /-18V by simply changing two components. The maximum output current must not exceed 100 mA each branch. If you ask, where the transformer and diode rectifier?This circuit is intended to be transplanted into an existing circuit (eg audio amp), which already provides symmetric voltage between + /-20V and + /-50V.
