Therefore, it has a smoothing effect and even things out. We don’t want any ac noise ripple imposed on the DC line voltage. 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 2 is Ground.

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.

Okay, now let’s build the circuit. This capacitor is there again to filter out any noise or high-frequency ac signals that may be on the DC voltage line. Essentially, it acts as a load balancer. In this article, we use a positive voltage regulator, which outputs 5V, the LM regulator. Also, design changes when dealing with the intended use of the circuit. The second capacitor, the 0.

But if you’re going to have a varying load, a potentiometer, for instance, on the output, it is well advised to add an electrolytic capacitor in parallel to the ceramic capacitor.

However, for experimental purposes and ease of getting parts, we will use a 9-volt battery as our input voltage.

datadheet 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. If you don’t have all the parts, don’t feel bad. 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.


It hooks up to the ground in our circuit. Okay, so let’s recap on 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.

How to Connect a Voltage Regulator in a Circuit

Adtasheet this article, we go over how to connect a voltage regulator to a circuit to get a specific DC output regulated voltage. That’s why it’s a good idea to get into hooking up a voltage regulator properly from the sart.

In this case, we are using a LM, which outputs 5 volts. After it comes out of the regulator, the other capacitor, the 0. This produces a voltage of 9 volts.

At the end of this experiment, when our circuit is hooked up, we’re going to read out the voltage with a multimeter and it should give out close to 5 volts. In order for the regulator to output 5 volts, the voltage entering has to be at least 2 volts higher, so it has to be at least 7 volts.

The voltage regulator works best and will be most efficient when a clean DC signal is fed into it. More will be on this for more advanced projects, but this page is a good start for those starting off in connecting voltage regulators for basic circuits. 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.

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.

The first capacitor, the ceramic daatsheet. 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. This is the pin that gives out the regulated voltage, which, in this case, is 5 volts.


Remember, the input voltage has to be larger than the voltage that the regulator regulates out. Sign up for Our Newsletter Name: The capacitor, in essence, acts as a bypass capacitor.

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 LM78XX voltage regulators are a popular kind for 78099ct and outputting positive voltage, while the LM79XX are a popular series of regulators for datasbeet voltage. This capacitor is there to filter out any noise coming from the voltage source the battery. Pin 1 is the Input Pin. 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. This electrolytic capacitor acts as a smoothing capacitor, when load resistance changes cause abrupt voltage spikes and drops, in a circuit. A voltage regulator is a 3-terminal device.

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.

Before we can hook up the circuit, let’s first go over the pinout diagram of the voltage regulator, which is vital for hooking up the circuit. 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. For now, you can just follow along.

Let’s view datashdet complete circuit now and explanations will ensue. 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.
