Is a linear power supply better?
Although the linear power supply is generally not as efficient as a switch-mode power supply (SMPS), they do afford better performance. If you scrutinize the electronics landscape, you will see the widespread use of linear power supplies in applications that require strict noise mitigation.
Why is it called a linear power supply?
Linear regulated power supplies gain their name from the fact that they use linear, i.e. non-switching techniques to regulate the voltage output from the power supply. The term linear power supply implies that the power supply is regulated to provide the correct voltage at the output.
What are the advantages of the linear power supply?
Advantages for linear mode power supplies include simplicity, reliability, low noise levels and low cost. These power supplies, also known as linear regulators (LR), have a very simple design in that they require few components making it an easy device for design engineers to work with.
