What is the difference between regulated and unregulated power supplies?

What's the difference between a regulated and unregulated power supply? While regulated power supplies regulate the output voltage, unregulated power supplies do not. In contrast to regulated power supplies, they provide the same level of power no matter what, meaning the output voltage will decrease as the load current increases, and vice versa.

Does a regulated power supply affect the output voltage?

Any variation in the input voltage will not affect the output voltage because of a voltage stabilizing device called voltage regulator used. The output voltage of an unregulated power supply, on the contrary, is not regulated meaning the output voltage changes as the load varies so they do not have voltage regulation.
