Now this DC voltage, clean and crisp, is ready to power whatever you want it to, in this case, the load is a resistor and a LED.
Okay, now let’s build the circuit. So for instance, if you have daasheet 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.
This capacitor is there to filter out any noise coming from the voltage source the battery. This capacitor is there again to filter out any datasheer or high-frequency ac signals datashet may be on the DC voltage line. The LM78XX voltage regulators are a popular kind for regulating and outputting positive voltage, while the LM79XX are a popular series of regulators for negative voltage. Without ground, the circuit couldn’t be complete because the voltage wouldn’t have electric potential and the circuit wouldn’t have a return path.
If you don’t have all the parts, don’t feel datazheet. We don’t want any ac noise ripple imposed on the DC line voltage. The first capacitor, the ceramic 0. Keep in mind that the design of a voltage regulator depends on the voltage regulator being used and the intended use of a circuit. Usually the only external components necessary are just capacitors, though heat sinks may also need to be added when heat dissipation is necessary.
Let’s view the complete circuit now and datashet will ensue. For now, you can just follow along.
How to Connect a Voltage Regulator in a Circuit
The second capacitor, the 0. Datashheet it comes out of the regulator, the other capacitor, the 0. More will be on this for more advanced projects, but datashset page is a good start for those starting off in connecting voltage regulators for basic circuits. Also, design changes when dealing with the intended use of the circuit. This capacitor charges up with voltage when the circuit has excess spikes in current and discharges to supply voltage when the circuit is low on current.
In this article, we use a positive voltage regulator, which outputs 5V, the LM regulator. Okay, so let’s recap on the circuit. Pin 2 is Ground.
This produces a voltage of 9 volts. In this case, we are using a LM, which outputs 5 volts.
Therefore, it has a smoothing effect and even things out. However, for experimental purposes and ease of getting parts, we will use a 9-volt battery as our input voltage. Essentially, it acts as a load balancer. In this article, we go over how to connect a voltage regulator to a circuit to get a specific DC output regulated voltage.
The capacitor, in essence, acts as a bypass capacitor. Pin 1 is the Input Pin.

daatsheet How to Connect a Voltage Regulator in a Circuit In this article, we go over how to connect a voltage regulator to a circuit to get a specific DC output regulated voltage. The voltage regulator should always be fed as smooth of a DC signal as possible which gives the best regulated output so it can regulate it down to its specified voltage. Remember, the input voltage has to be larger than the voltage that the regulator regulates out.
It shorts this noise to ground and allows the pure DC signal into the regulator. You can buy them at anytime and come back to this page and do the experiment anytime. It shorts the AC signal of the voltage signal which is noise on the voltage signal daasheet ground and only the DC portion of the signal goes into the regulator. 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 datassheet 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.
It hooks up to the ground in our circuit. A voltage regulator is a 3-terminal device. Depending on the voltage regulator in use, we can get a regulated positive or negative voltage, at whichever voltage we want.
The circuit begins at the 9-volt battery. Always consult the Manufacturer’s Datasheet for the voltage regulator in use for a circuit to see how to hook it up with the necessary required external components. This electrolytic capacitor acts as a smoothing capacitor, when load resistance changes cause abrupt voltage spikes and drops, in a circuit.
The first capacitor, the 0. The Datasheet specifies which value of capacitors to use, so it’s a good idea to learn from the people who manufacturered the chip. Pin 3 is datasyeet Output Pin.
The output voltage of whatever voltage source you want to regulate down whether it’s a transformer, battery, etc. The regulator regulates this voltage down to 5 volts.
The voltage regulator works best and will be most efficient when a clean DC signal is fed into it. When the load of a circuit is stable and unchanging, as in the example above, it is usually not necessary to add a large electrolytic capacitor on the output to act as a smoothing capacitor.
