Essentially, it acts as a load balancer. Sign up for Our Newsletter Name: Therefore, it has a smoothing effect and even things out.

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.

After it comes out of the regulator, the other capacitor, the 0. 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. For now, you can just follow along. 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.

The second capacitor, the 0.

The output voltage of whatever voltage source you want to regulate down whether it’s a transformer, dagasheet, etc. The Datasheet specifies which value of capacitors to use, so it’s a good idea to learn from the people who manufacturered the chip. The voltage regulator works best and will be most efficient when a clean DC signal is fed into it.

Pin 1 is the Input Pin. This capacitor is there again to filter out any noise or high-frequency ac signals that may dagasheet on the DC voltage line. Without ground, the circuit couldn’t be complete because the voltage wouldn’t have electric potential and the circuit wouldn’t have a return darasheet.

Remember, the input voltage has to be larger than the voltage that the regulator regulates out. We don’t want any ac noise ripple imposed on the DC line 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.

How to Connect a Voltage Regulator in a Circuit

Okay, now let’s build the circuit. However, for experimental purposes and ease of getting parts, we will use a 9-volt battery as our input voltage. In this case, we are using a LM, which outputs 5 volts. 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.

Now this DC voltage, clean and crisp, is ready to power whatever you want it to, 7809cg this case, the load is a resistor and a LED. In this article, we use a positive datahseet regulator, which outputs 5V, the LM regulator.

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.

This capacitor is there to filter out dtaasheet noise coming from the voltage source the battery. If you don’t have all the parts, don’t feel bad. It shorts this noise to ground and allows the pure DC signal into the regulator.

At the end of this experiment, when our circuit is hooked up, we’re going to read out the voltage with dahasheet multimeter and it should give out close to 5 volts. In this article, we go over how to connect a voltage regulator to a circuit to get a specific DC output regulated voltage. 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.

It hooks up to the ground in our circuit. This produces a voltage of 9 volts. Keep in mind that the design of a voltage regulator depends on the voltage regulator being used and the intended use of a circuit.

In order for the regulator to output 5 volts, the voltage entering has to be at least 2 volts higher, so it datasheeet to be at least 7 volts. Pin 3 is the Output Pin. datasyeet

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.

The regulator regulates this voltage down to 5 volts. Pin 2 is Ground. 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. This is the pin that gives out the regulated voltage, which, in this case, is 5 volts.

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. Okay, so let’s recap on the circuit. The capacitor, in essence, acts as a bypass capacitor.

This electrolytic capacitor acts as a smoothing capacitor, when load resistance changes cause abrupt voltage spikes and drops, in a circuit.
