Question A-004-003-005

What type of linear voltage regulator is used in applications requiring a constant load on the unregulated voltage source?

Correct Answer

A shunt regulator

Explanation

A shunt regulator maintains a constant output voltage by shunting (diverting) varying amounts of current to ground through a control element parallel to the load. This presents a relatively constant load to the unregulated source if the total current (load + shunt) is kept high.
