This project is a solution to power up most of devices or projects requiring dual (+/-) adjustable power supply. The circuit is based on LM317 positive and LM337 negative voltage regulators. LM3X7 series of adjustable 3 terminal regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V DC output range. On board TO220 Package with heat sink can handle maximum load current. Board provided with two on board preset to adjust the voltage.

The circuit has resistor values too high and is missing two protection diodes shown on the datasheets.
