Voltage Regulators: An Introduction

We finish off our Introduction to Electronic Components series with the voltage regulator, which is a useful little thing. Sometimes, you have more voltage than you need—say, when you’re working with a 9 volt battery but you need 5 volts for your circuit. Also, if your project is especially finicky, they can also take in a fluctuating amount of voltage and emit a perfectly constant value.

If you’re looking for more about other components (say…diodes, buttons and switches, resistors, etc etc) check out the whole playlist!
