Q. What is a DC regulated power supply?

Answer

A user can think of a regulated DC power supply as an unregulated power supply with an added voltage regulator. As long as the load current doesn't go over the specified limitations, the voltage will remain constant. It is possible to feed AC, DC, battery, or very low voltage into a DC power supply control subsystem. The four main components of a regulated DC power supply are a step down transformer, rectification, DC filtration, and regulation. There are two main types of DC power supply architectures: unregulated and regulated. There is an option for linear regulation of the power supply, or switching.
