7912 Pinout and Simple Circuit Diagrams

Electronics

LM 7912 belongs to 79xx family of voltage regulator ICs and is very commonly used in such power supplies where 12V negative voltage output is required. 7912 is almost a standalone regulator IC. The reason why I used the word almost is because although it ...
LM317 Pinout and Basic Circuit Diagram

Electronics

LM317 is a famous linear voltage regulator IC. It provides very stable, uniform and smooth output which does not fluctuate with load changes. It can also be used as a precise current limiting device which is essential for testing electronic equipment. Un...
Circuit Breaker vs Fuse, Which One is Safer and Reliable?

Electronics

Circuit breakers have relaxed us by eliminating the need to physically replace the fuse after every short circuit or overload event. This certainly is an advantage but if you are thinking that you won’t miss the good old fuse then you are certainly wrong....
Resistors Their Types and Their Color Code Diagram

Electronics

In this tutorial I am going to teach you about resistors, their usage and functionality, types of resistors and how to read their color code. In addition to that I am also going to show you a very basic and simple circuit to practically explain resistor’s...
7805 Pin Configuration and Voltage Regulator Circuit

Electronics

7805 is an easy to use voltage regulator IC which outputs 5v rated at 1A max. It takes an unregulated DC voltage input which can be fluctuating within its input limits and converts this fluctuating voltage input into a perfectly regulated 5 volts power ou...
7812 Pin and Circuit Diagram

Electronics

7812 is a famous IC which is being widely used in 12V voltage regulator circuits. Truly speaking it is a complete standalone voltage regulator. We only need to use two capacitors, one on the input and second one on the output of 7812 in order to achieve c...
Voltage Regulator Circuit

Electronics

Voltage regulation means to prevent the voltage from dropping down or rising above a specific value. A 12 volt regulator circuit will provide exactly 12V under load as well as without load. On the other hand, an un-regulated 12V power supply output voltag...
7809 Pin and Circuit Diagram

Electronics

7809 is a voltage regulator integrated circuit(IC) which is widely used in electronic circuits. Voltage regulator circuit can be manually built using parts available in the market but it will take a lot of time to assemble those parts on a PCB. Secondly, ...
How to purchase a Solar Panel?

Energy

Solar panel is a poer source just like a battery or an electric generator except that it generates energy only when exposed to sunlight. Solar panels are capable of generating electricity without polluting our environment therefore in my opinion solar ene...
Inverter Circuit Diagram

Energy

Power inverter is a very useful device which can convert Low voltage from a DC sources to high voltage AC. The most common power inverter is 12V to 240V inverter. Perhaps that is because 12V batteries are common and easily available. This type of power in...
