How do you build a 5.0V regulated power supply?

  1. Sep 18, 2006 #1
    i am stuck. i have no idea how to start on this project. I have to build a power supply that produces 5.0V regulated. i can't use regulators so i have to build it but i have no idea how to get started. i have an ac course to start with. i would appreciate any ideas, insights or designs you might have.

    What do you mean that you "have an ac course to start with"? Does that mean that you have taken an AC electronics course in school, or does that mean that you need to design and build your power supply to run off of the AC mains 120/240Vrms power?

    What topologies are you considering for your design? When you "have no idea how to start on this project", a good starting point would be your textbooks, or wikipedia.org:
