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.

Gail Borden Public Library in Elgin, IL is planning a "Don't Tell Mom" program for June 14, in which we'll have hands-on science, tech, hardware, etc. activities for kids and their parents. We want to do things that are cool and "dangerous".

Chibots has registered to attend the Museum of Science and Industry's Robot Block party during National Robotics Week. All are welcomed to attend. For those that want to display or bring in a robot, please let us know so that I can inform the MSI contact.

Information that has been sent to us as an attachment has been included at the bottom of this event description.

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.
