This circuit is a small +5V power supply, which is useful when experimenting with digital electronics. Small inexpensive wall transformers with variable output voltage are available from any ...

The goal of the project is to create a micro PSU to provide power on a breadboard with 5 Volts supply as the whole circuit can be connected to 9V battery, 12V or any other DC power source from 8 to ...

This three-part mini tutorial gives an overview of the possibilities for power-supply design. It addresses the basic and commonly used isolated and non-isolated power-supply topologies along with ...
