This electrolytic capacitor acts as a smoothing capacitor, when load resistance changes cause abrupt voltage spikes and drops, in a circuit. Essentially, it acts as a load balancer. If you don’t have all the parts, don’t feel bad.

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. In this article, we go over how to connect a voltage regulator to a circuit to get a specific DC output regulated voltage.

How to Connect a Voltage Regulator in a Circuit

The voltage regulator works best and will be most efficient when a clean DC signal is fed into it. Okay, now let’s build the circuit. A voltage regulator is a 3-terminal device. 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. Depending on the voltage regulator in use, we can get a regulated positive or negative voltage, at whichever voltage we want.

Pin 2 is Ground. For now, you can just follow along. We don’t want any ac noise ripple imposed on the DC line dtaasheet. In this article, we use a positive voltage regulator, which outputs 5V, the LM regulator.

After it comes out of the regulator, the other capacitor, the 0.

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. In this case, we are using a LM, which 789ct 5 volts. The Datasheet specifies which value of capacitors to use, so it’s a good idea to learn from the people who manufacturered the chip.

But if datasheeg going to have a varying load, a potentiometer, for instance, on the output, it is well advised to datashet an electrolytic capacitor in parallel to the ceramic capacitor. This capacitor is there again to filter out any noise or high-frequency ac signals that may be on the DC voltage line. 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.

However, for experimental purposes and ease of getting parts, we will use a 9-volt battery as our input voltage. Pin 1 is the Input Pin. Also, design changes when dealing with the intended use of the circuit.

78009ct why it’s a good datasjeet to get into hooking up a voltage regulator properly from the sart. 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. Remember, the input voltage has to be larger than the voltage that the regulator regulates out.

How to Connect a Voltage Regulator in a Circuit

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. 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. Therefore, it has a smoothing effect and even things dahasheet. Keep in mind that the design of a voltage regulator depends on the voltage regulator being used and the intended use of a circuit. This capacitor charges up 7809t voltage when the circuit has excess spikes in current and discharges to supply voltage when the circuit is low on current.

The first capacitor, the 0. Datsheet capacitor is there to filter out any noise coming from the voltage source the battery. The regulator regulates this voltage down to 5 volts. This produces a voltage of dqtasheet 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.

It hooks up to the ground in our circuit. Sign up for Our Newsletter Name:
