## Introduction: 5 Volt Regulator

Hi, this is a simple circuit for a 5 volt regulator with a input voltage from 8 to 12 volts.
just follow the circuit diagram and you"ll be fine.

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

## Step 1: Parts

The things you need:

1x TS7805 5 volt regulator
2x 1uf capacitor
1x power plug (or other connector)
1x 220 ohm resistor
1x Blue LED (I used a diffused one)
1x Mirco Switch
2x connector

*The LED, switch and two connectors are optional, make it how you want.
*You could even add a cooling van for higher voltages!

Follow the schematics  at the pictures and make sure it works on a breadbord if you have one before soldering it on a PCB.

## Step 2: Using the Regulator

I use my regulator to power my breadboards!

Kan je mij uitleggen waarom de capacitors erbij zitten, ik heb deze schema's ook gezien zonder capacitors.

Hi!

I was wondering... what happens to the output voltage/current when the input voltage is 5v?

You will be quite dissapointed if you follow the schematic.

I see what`s wrong, the LED is placed wrong, it must be connected before the regulator :) Or isn't it?

No, it, and it's resistor must go from + plus to - minus, as it does on the upper drawing (which is correct)).

I see what you mean :) i will change it tomorrow, thank!s :)
