Linear Voltage Regulators

Linear voltage regulators are simple voltage regulator circuits designed to compare and maintain a steady constant output voltage with a precise reference voltage. These devices are comprised of resistors and diodes to maintain a steady voltage along their terminals. These devices are step-down converters; they keep the output voltage lower than the input. Some linear voltage types include regulators with the capacity to regulate voltage while the power supply voltage is close to the supply voltage.

How do linear voltage regulators work?

For the maintenance of constant voltage across output terminals, the linear voltage regulators use a feedback loop (closed). They feature negative-feedback controlled transistors for generating specialized output voltages that remain stable, avoiding any fluctuations in input voltages and load currents.

What are the benefits of linear voltage regulators?

Linear voltage regulators offer various advantages. They are typically highly integrated, easy to use, have low input noise, and are low-cost with maximum flexibility. Furthermore, they offer less noise output than other regulators. 

Types of linear voltage regulators:

There are two types of linear voltage regulators based on the connection load: Series regulator and Shunt regulator.

  • Series Regulatorconnected in series with the load designed to stabilize the output voltage of a regulator.
  • Shunt Regulatorconnected in parallel to the load, designed to stabilize the output voltage of the device.

Where are linear voltage regulators used?

These regulators are mostly found in a wide variety of applications and multiple devices, such as:

  • Industrial applications
  • Automotive applications
  • Mobile phone
  • Computers
  • Laptops
  • Mobile chargers
  • TVs
  • Power generator systems
  • Solar panels/power plants.
