Voltage Regulation, Part 3 of 3

This last part presents some discussion aout voltage ripple.

The Output Ripple

The regulator is able to provide the required voltage as it is adjusted using the variable resistor, but sometimes the voltage is not as clean as it is needed. How much this affects the functionality of the circuit depends on the application. In some cases the unclean voltage has no effect, but in others it can wreak havoc and create a scenario that is difficult to troubleshoot.

Voltage Regulation, Part 2 of 3

This part describes the circuits using the four regulators and the loads described in the first part



This switching regulator provides 500 mA of current to the circuit. This makes it ideal for small electronic circuits that don’t demand much. It has a peak current output of 1.5 A which means that it can provide 1.5 A of current, but only for a short period of time.

Voltage Regulation, Part 1 of 3

Voltage Regulation


Voltage regulation is a way of adapting a source voltage to a voltage that can be used by the circuit that needs to be powered. The circuit may require 3.3 or 5 VDC, but your power supply delivers 12V. What to do? Luckily there are various ways to lower, or step down, that original 12VDC to a more usable 3.3 or 5 VDC, depending on your circuit’s needs.

Capturing Ideas for Competition Table

Please post your table ideas as comments on this article. Be as specific as you can and include links to any examples or sources for your idea. We won't spend a lot of time debating ideas now, let's capture everyone's thoughts and the team will start sorting through them once they are assembled.

If you foresee pros and cons for your idea, please list those as well.


Exhibitors at conventions set up and break down tables regularly. We could look at suppliers of exhibitor equipment and see if anything fits the bill.
