This is to make sure that voltage is, in fact, being supplied to voltzge regulator. As an example, we’ll use the popular voltage regulator, the LM This is why we do this test.

The voltage that we should read should be higher than the voltage the regulator is rated to output. If we read a higher voltage, then the voltage regulator is receiving sufficient voltage to regulate down.

The LM is a voltage regulator is rated to output 5 volts, so we should read this output. Unlike fixed voltage regulators, adjustable regulators can be regulated to output adjustable voltages. To measure the output voltage, we place the same multimeter set in the DC voltage setting and now place the positive probe of the multimeter on the output pin of the voltaage and the negative probe on the ground pin of the regulator.

To eb11a the voltage going into the voltage regulator, we take a multimeter and place it in the DC voltage setting.

How Regulato Test a Voltage Regulator A voltage regulator is a device that takes in an input voltage and regulates it down to the voltage that it is rated for.

If we don’t read the correct voltages, then more than likely it is a defective regulator.

The DC voltage setting is the setting of the multimeter that has the following symbol or sign. Measuring the Output Voltage Voltsge that this step is complete, we now read the output voltage. Measuring the Input Voltage When testing the voltage of a voltage regulator, we first check the voltage from the input pin to ground.

If we do not, then the voltage regulator vvoltage defective, as it does not do the job it was designed for, which is output a regulated voltage. If the multimeter does read a voltage near its rated output voltage, the voltage regulator is functional and is good. And the regulated output voltage comes out from pin 3 Output.

The ground pin is pin 2. A voltage regulator is a device that takes in an input voltage and regulates it down to the voltage that it is rated for. We should now read a voltage at or about the rated voltage that the regulator is designed for.

Before we get into how to read the voltages with a multimeter, first we’ll go over the pinout of a voltage regulator, so that you’ll know which pins to read voltages from. If the regulator isn’t receiving sufficient voltage, of course it will not be able to output its rated regulated voltage.

So we’ll now go through specifically how to test a voltage regulator.

The input voltage that needs to be regulated down goes into pin 1 Input. If the regulator is rated to output 5 volts, then we should read a voltage very near 5 volts coming out from its output. An adjustable regulator can be tested in the same way.

We check the voltage input into the voltage regulator and the voltage output from the regulator. All a user must do is calculate the output that voltagd regulator should output and perform the same test as is shown above to see whether it is good or defective. Being that a voltage regulator passes out a regulated output voltage, the only test we must do to check a voltage regulator is a voltage test.

This is normally volts higher. We take the probes of the multimeter and place the positive probe normally the red probe on the input pin of the voltage regulator and the voltagee probe normally rsgulator probe on the ground pin. Below is the pinout of the LM voltage regulator: If we read at the input pin the voltage which we feed into the regulator and read at the output pin the output voltage which the regulator is rated for, then we know that the voltage regulator is good.
