The circuit presented here is a very simple and easy to build Lab Power Supply. The output of this power supply is adjustable from 0 to 10V DC, and it has current limit control up to 3A. Two Trimmer potentiometers are provided to adjust the voltage and current. The input supply is DC 12V to 18V 3A or AC12V /3A. The screw terminals help to connect the input and output connections, and a large area on PCB provided as heat spread so no external heatsinks required. The power supply also includes over-temperature protection. The board is built using 2 x LT3083 chips, U1 is used as a current source and U2 provides adjustable output voltage.
