What is a Voltage Regulator IC?

The voltage regulator IC is a semiconductor chip consisting of voltage regulator circuits inside it. It has a metallic terminal brought outside to connect with external power circuits. So if you do not want to build a voltage regulator circuit by connecting different components then just purchase a specific voltage regulator IC and connect it to the circuit.

There are two types of Voltage Regulator ICs are available in the market,

Fixed Voltage Regulator - Fixed Voltage regulators are those that provide a constant output voltage and we cannot vary the voltage as per our requirement. For example, LM7805 is a fixed voltage regulator IC that always provides a fixed 5V output voltage.

Adjustable Voltage Regulator - Adjustable voltage regulators are those where we can adjust or vary the output voltage as per our requirement by connecting an external component such as a potentiometer. For example, LM350 is an adjustable voltage regulator IC. Here we can adjust the output voltage from 1.2V to 33V.

Remember that the IC number is very important. In the above section, we have given a voltage regulator IC list with their features in a short. So first of all, select the IC number according to your requirement, then go to purchase with that particular IC number. But keep in mind that, before connecting a voltage regulator IC to your circuit must check the Datasheet to make sure if it is suitable for your applications.
