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.
In simple words, the main difference between a fixed voltage regulator and an adjustable voltage regulator is that a fixed voltage regulator provides a constant, pre-set output voltage (e.g., 5V, 12V) and cannot be changed whereas an adjustable voltage regulator allows the output voltage to be varied within a specific range by adjusting an external resistor or potentiometer.
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.
