Linear Regulator

A DC/DC converter that stabilizes the voltage is often referred to as a voltage regulator.

Two types of regulators exist, classified by a conversion method: linear or switching.

Linear Regulator

As its name suggests, a linear regulator is one where a linear component (such as a resistive load) is used to regulate the output.

It is also sometimes called a series regulator because the control elements are arranged in series between the input and output.

Linear Regulator
Advantages Disadvantages
  • Simple circuit configuration
  • Few external parts
  • Low noise
  • Relatively poor efficiency
  • Considerable heat generation
  • Only step-down (buck) operation
