How do you hook up a voltage regulator
About the Author This article was written by the It Still Runs team, copy edited and fact checked through a multi-point auditing system, in efforts to ensure our readers only receive the best information. This wire will be the connection to the positive or supply wire to your device.
That's why it's a good idea to get into hooking up a voltage regulator properly from the start. The second capacitor, the 0. This Instructable is mostly for the novice, I've tried to cover every detail but is probably overkill for anyone with prior electrical wiring experience.
In this article, we go over how to connect a voltage regulator to a circuit to get a specific DC output regulated voltage.
A voltage regulator takes current from a battery with oscillating voltage and puts out constant voltage.
Step 1: Parts List
The pictures are great, but will take me a while to decipher. Touch the other end of the wire to the field terminal. In this simple tutorial I'm going to show how to wire a voltage regulator with a potentiometer to adjust the output voltage.
Simply remember the respective connections. So for instance, if you have 10 volts coming from a transformer that you want regulated down to 5 volts, the output of the transformer the 10 volts is fed into the regulator input pin 1 so that the regulator can regulate it down to your wanted voltage 5 volts.
Remove the battery after this step. Follow the regulator manual's mounting instructions for the proper positioning of the mount. Typically, this requires four screws or bolts and four washers and nuts. It shorts the AC signal of the voltage signal which is noise on the voltage signal to ground and only the DC portion of the signal goes into the regulator.
Sometimes both the alternator and regulator markings say 1 and 2 or the regulator says F and R instead of the alternator. In this article, we use a positive voltage regulator, which outputs 5V, the LM regulator.
Introduction: Wiring an Adjustable Voltage Regulator
Attach the regulator to the mount. If you only need it to be 1.
The regulator regulates this voltage down to 5 volts. At the end of this experiment, when our circuit is how do you hook up a voltage regulator up, we're going to read out the voltage with a multimeter and it should give out close to 5 volts. Like, you can only fill the barrel from the open end. Let's view the complete circuit now and explanations will ensue.
It hooks up to the ground in our circuit. For a circuit like this, where we're lighting an LED, it isn't exactly crucial to have a pure DC signal, but in other applications, such as when outputting voltage to power a logic chip, which needs a precise voltage fed into it in order to give the correct logic output, it is crucial.

One end will go to the out pin the other will go to ground. Each frame is numbered in the left hand corner and will coincide with each numbered step.
Connect the generator or alternator wire to the regulator. I'm using an LMT which is readily available and versatile. Connect the positive battery cable wire -- usually red -- to the regulator. The less functional a project is, the more I'm interested in it This capacitor is there to filter out any noise coming from the voltage source the battery.
