Voltage Regulator

A voltage regulator is an electronic device that maintains a constant voltage level. It helps to protect sensitive electronic devices and prolong the life of the equipment.

Voltage controllers are also called AC controllers or AC regulators. As the name suggests a voltage regulator regulates the voltage or generates a fixed output voltage of the present magnitude that remains constant regardless of the varying input voltage. 

Voltage controllers are made of BJT or MOSFET pass devices which are controlled by a high gain differential amplifier. It compares the output voltage to a precise reference voltage and adjusts the voltage to maintain a constant voltage. 

Voltage regulator circuit

Voltage regulators in a circuit form are represented as voltage regulator circuits. They keep voltage within a certain range and are compatible with other electronic components. 

Voltage regulator circuit types

1. Linear Voltage Regulator Circuit: 

A high-gain operational amplifier regulates an active pass device (such a BJT or MOSFET) used in a linear voltage regulator. The linear regulator adjusts the pass device resistance by comparing the internal voltage reference to the sampled output voltage and then driving the error to zero in order to maintain a constant output voltage. Linear regulator voltage circuits are examples of step down converters. Hence the output voltage is always less than the input voltage. 


2. Switching Regulator: 

They are more versatile than linear regulators, they can be used as step up or step down or both step up and step down converter. These switching regulators are highly efficient, and they can support higher current and have wider Vin and Vout applications. This voltage regulator circuit can achieve more than 95% efficiency depending on the application requirements.

1. Which voltage regulator is best?

To choose a good voltage regulator or the best one for your project, you need to consider the following factors. 

  1. Input and output voltage 
  2. Drop out voltage 
  3. Select if you are using a linear regulator or switching regulator. 
  4. Device sensitivity 
  5. Your response time 
  6. Power draw

2. What voltage regulator do I need?

Start by presuming a linear regulator can be utilized if the input voltage is higher than the output voltage when choosing a voltage regulator for your system. Use a buck switching regulator only if doing so wastes too much power. Use a boost switching regulator if you need an output voltage that is higher than the input voltage.

3. How big of a voltage regulator do I need?

With fixed regulators, a wide variety of output voltages from 3.3V to 24V is accessible, including pleasant values like 5V, 6V, 9V, 15V, and 18V. This series of regulators works well for the majority of applications; depending on the packaging, they can handle input voltages of up to almost 30V and output currents of up to 1A.
