How to Test 78L05 Voltage Regulator

A voltage regulator is a component that maintains a fixed amount of output voltage regardless of the input voltage. You can find voltage regulators in the power supplies of computers and other electronic devices. Whenever DC voltage stabilization is required, a voltage regulator is likely going to be used to perform that action.

The 78L05 voltage regulator is one specific type of voltage regulator. The “78” number identifies it as a positive voltage regulator, while the “05” signifies the output voltage is 5 volts. It is a three-terminal voltage regulator, which includes the input terminal, ground terminal, and output terminal.


A voltage regulator test will determine the amount of voltage going into the voltage regulator and the amount of voltage going out of the regulator (input and output). You will need a multimeter to conduct a measurement of the input voltage and output voltage. It is an electronic measuring instrument designed to measure resistance, voltage, and current.

When you’re ready to perform the test, you can start by testing the input voltage. Switch the setting on the multimeter to “DC voltage.” It should have a “V” symbol or something similar. You’ll see the multimeter has a positive probe and a negative probe. Attach the positive probe to the input pin on the bottom of the voltage regulator. Then attach its negative probe to the ground pin.

The multimeter has a digital screen that will indicate the amount of voltage. The input voltage should be higher than the output voltage by about 1 to 2 volts. You can find out by performing a similar measurement of the output voltage. All you need to do is take the positive probe off the input pin and place it on the output pin. You can leave the negative probe on the ground pin.

The amount of output voltage indicated should be 5 volts because of the “05” associated with 78L05. If you see a different number other than 5, then your voltage regulator is defective.

Single-Chip Microcomputer

The best way to define a microcomputer is by its size, price, and capability. In terms of size, it is relatively smaller than a microprocessor and micro-controller. It is relatively inexpensive. It is a limited capability computer.

A single-chip microcomputer has the same architectural structure found in computers. The size of the microcomputer has continuously been reduced, and nowadays you will find their size being similar to the size of a notebook.

They can be accessed easily because of their relatively cheaper price. However, they are not very powerful and have limited internal operations and instructions. One of the best examples of a microcomputer is the Commodore 64, which was the bestselling model.


Defined by size and cost, a micro-controller is small and of low cost. It has a special design for performing specific tasks such as receiving remote signals and displaying microwave information.

An ideal micro-controller should have the processor, memory (RAM, ROM, and EPROM), peripherals (timers and counters), serial ports, etc.

There are various types of micro-controllers such as Bit, Memory, and Instruction Set. These types have their subcategories, which define how they are used further.

Micro-controllers have various functions such as light sensing, temperature sensing, fire detection, and measuring devices.


The main function of a microprocessor is to process micro-instructions. The instructions are coded in the form of 0s and 1s.

Usually, the microprocessor is available as a single integrated circuit. The main components of a microprocessor are the Arithmetic Logic Unit (ALU) and the Control Unit (CU). An example of a microprocessor is Intel 8085.

A microprocessor is more effective than both the microcomputer and micro-controller because of its wide range of uses and its flexibility in configuration. It is also more expansive than the two because of their performance and complexity.

How to Make Earphone and How does Earphone Works

There is nothing as exciting as making your earphones and using them. It might look complex, but the science of how earphones work is very easy to understand. Once you understand it, you can easily make your earphones.

How Do Earphones Work?

Before we look at the ways in which you can make your earphones, let us first discuss how they work.

Here are some basic principalities of how an earphone works:

It’s all about completing the circuit

At its basic level, an earphone is all about completing the circuit. In as much as an earphone may look so complex, it is just a loop of wire with currents passing through it. Electric currents interact with a magnet that pushes the air, which produces the sound. So, to produce electric currents, you must complete a circuit.

Parts of earphones

To understand how earphones work, you will need to know the different parts of earphones and their work in helping to produce sound.


Speakers of earphones are just like other speakers, just that they are smaller and put very close to your ears. They are usually too small that they fill the ear’s outer void.


Transducers are the devices responsible for converting energy from one form into another. In an earphone, there are two transducers that convert your device’s energy into sound energy. Just like any other circuit, an earphone has a conductor that draws energy from the source and provides it to the load, which is the transducer.

The Jack

The jack is what connected the conductor to the source. The tip of the jack has the sleeves that power the right and left earphones.
