This is a common bench power supply using voltage regulators to output voltage from 0 to 10 volt.
I am providing a circuit design of the voltage regulator used in this project.
One important thing to keep in mind while designing such a power supply is connections. Improper wiring connection can damage the transistors.
Following picture shows which binding posts gives out what voltage…
