    I am supposed to perform certain calculations to get the desired outputs and then design and test my circuit on a software before I start building it. I am not asking anyone to do my project for me, I just need directions on how to go about the calculations and eventually designing my circuit on a software.
    Any tutorials or video resources or personal tips? Please?
    The project question is uploaded as an attachment. I circled the question which pertains to me. Also, I am supposed to choose only one of the outputs,not all of them. Thank you!

    If you ask an OP to put this in the Homework sub-forum, you will likely get higher quality help, especially if you are willing to put good effort into it.

    Also, remember that a constant voltage can be had from passing a constant current through a resistor (ohms law). So, look up how to make a constant current source from two resistors and two transistors.

    Is this using a Linear transformer, or switch mode psu?

    Pick one and tell us which it is.
