August 13 2009 		This adjustable power source uses the LM350K voltage regulator.
With this IC it is possible to obtain an output voltage from 1.2 to 33 volts with a 3 amps maximum current.
In order to protect the voltage regulator, it must use a heatsink.

Components

- Transformer (110 or 220V)/24V - 3 amps
- LM350K voltage regulator
- 4 rectifier diodes (1N5404)
- 1 4700 uF / 50V electrolytic capacitor
- 1 47 uF / 50V electrolytic capacitor
- 2 100 nF capacitors
- 1 resistor 270 ohms, 1 watt
- 1 5K linear potentiometer.
