The linear regulator type system supplies the output voltage with high stability and low noise by using the series regulator. However, its efficiency is poor because all the voltage difference between the input and output is consumed as heat. Series regulators include band-gap type and Zener type, and each has unique characteristics in terms of output current, noise performance, and stability.
In addition, power transformers that transform commercial power inputs are generally large and heavy. And the series regulator needs a large heat sink for heat release.
