Does power supply issues cause limp mode?

A car is said to be in limp mode when it is traveling with a malfunctioning system and the car has limited the functionality of the system in order to protect it from further damage.

 

Some people refer to it as limp home mode which implies that it is meant to not leave you stranded but to carry you home where a repair should take place.

 

The power supply of a car is the source of electrical power to other parts of the car.
