The result is a neat and tidy power supply built out of readily-available components. We particularly like the addition of the stepdown converter – most ATX-based projects don’t offer variable ...

This simple variable power supply circuit has a low production cost and delivers an output voltage between 1,5 V and 15 V with a maximum current of 500 mA. Its stabilization is better than 2% if the ...

This variable power supply is using 7805, 7809, 7812 or 7815 voltage regulators, where the last 2 digits represents the maximum output voltage of the IC.
