EH11A VOLTAGE REGULATOR PDF

Zulkilar The LM is a voltage regulator is rated to output 5 volts, so we should read this output. This is normally volts higher. Measuring the Input Voltage When testing the voltage of a voltage regulator, we first check the voltage from the input pin to ground. 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.

Zulkilar The LM is a voltage regulator is rated to output 5 volts, so we should read this output. This is normally volts higher. Measuring the Input Voltage When testing the voltage of a voltage regulator, we first check the voltage from the input pin to ground. 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. 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 regulator and the negative probe on the ground pin of the regulator. To test the voltage going into the voltage regulator, we take a multimeter and place it in the DC voltage setting. And the regulated output voltage comes out from pin 3 Output. Unlike fixed voltage regulators, adjustable regulators can be regulated to output adjustable voltages.

All a user must do is calculate the output that the regulator should output and perform the same test as is shown above to see whether it is good or defective. The ground pin is pin 2. EH11A H11A AZH-ADJ 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.

We check the voltage input into the voltage regulator and the voltage output from the regulator. If we do not, then the voltage regulator is 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. 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.

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 negative probe normally black probe on the ground pin. This is to make sure that voltage is, in fact, being supplied to the regulator. The voltage that we should read should be higher than the voltage the regulator is rated to output. Below is the pinout of the LM voltage regulator: How To 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 read a higher voltage, then the voltage regulator is receiving sufficient voltage to regulate down. The input voltage that needs to be voltzge down goes into pin 1 Input. Measuring the Output Voltage Vltage that this step is complete, we now read the output voltage.
