10 pieces 5V Out, 6V to 12V In AMS1117-5.0 5.0V Step-Down Linear Voltage Regulator Module

In this video I'm going to talk about linear voltage regulators and show you how to use one to charge 5 volt USB devices like phones and MP3 players. So what is a voltage regulator? A voltage regulator is a device that takes an unregulated input voltage that could be fluctuating over time, and spits out a perfectly regulated constant voltage. For example here I have a twelve volt battery that will be 13.8 volts fully charged, and around 11 volts fully discharged. This 5 volt regulator will ensure that I get a constant five volts regardless of the input voltage. And the capacitors in the circuit will maximize the stability of the regulator's output. I'll show you the circuit on the bread board later on. In the meantime take a look at this. In an earlier video I showed you how to make unregulated DC power supplies. Right now the output of that unregulated supply is about 16 volts with ab
