All About Voltage Regulator

The voltage regulator is a common feature in many electrical circuits to ensure that constant and stable voltage supplied to the sensitive electronics. It is designed to maintain a constant level and is used as an electronic component or electromechanical mechanisms. 

The voltage regulator is vital for a stable and reliable voltage. They take input and generate a regulated output regardless of the input either at a fixed rate or adjustable rate.

This process is automatic regulation of the level of output is handled using various techniques including Zener diodes. It helps in improving the performance, reliability, efficiency, and other features such as increase output in various fields. 

It can be used to regulate one or more AC or DC voltages. Regardless of the purpose, if you want to know how the voltage regulator is operated in a variety of fields, visit

Linear regulator is used as a power transistor and a variable resistor that behaves like the beginning of a voltage divider network. The output is driven by the divider network is used as feedback for power transistors to maintain a constant level. 

With the help of linear regulators, the power dissipated by the resistor can be high which requires a good heat sink. A switching voltage regulator works on a different principle from other regulators, especially linear regulators.

By providing a constant output, the switching regulator stores energy at a set rate and ensures that the charge level is maintained with minimal ripple. 

This technique allows the switching regulators to be efficient when the energy storage circuit requires large amounts of energy.
