Voltage Regulator ic 78XX Tutorial with Practical Experiments

In this video, I have discussed different ratings and features of Voltage Regulator IC of 78XX series with different Practical Experiments, like the variation of input and output voltage with the variable load of 12v regulator ic [7812], testing the dropout voltage of 5v regulator ic [7805] with variable input voltage etc.

I will request you to watch the complete tutorial video of voltage regulator but you can also jump to any topic by click on the following Time Stamps:

00:27 What is a Voltage Regulator?

01:04 How to identify the voltage regulator ic [output voltage]

01:54 Pinout diagram of voltage regulator ic of 7800 series

02:18 Voltage regulator circuit

03:31 Variation of input and output voltage of 12v regulator ic [7812] with the variable load

05:37 Testing dropout voltage of 5v regulator ic [lm7805] with variable input voltage

07:50 How to calculate power dissipation in regulator ic [ When heat sink should be used]

10:02 Different ratings and features of Voltage Regulator IC of 78XX series from datasheet

In this video, I have used different voltage regulator ic, 7805, 7809, 7812, 7815, 7824 of 78xx series TO220 type to explain how these regulators can be used in circuit for different applications
I have also discussed some important ratings and features of these voltage regulators with some practical experiments.

The linear voltage regulators are not so efficient but the circuit is very simple. so it is widely used in different DC power supply, 5v, 9v, 12v, 24v etc.
It better to use a heat sink with regulator ic for higher power dissipation.
