Created: 5/13/2020Last Updated:5/13/2020

Definition

  • Regulated output means that the system is constantly stabilizing the output against a reference point regardless of line in and load conditions.
  • Unregulated output means that the system output can vary depends on line in and load conditions.

Key difference

Regulated device has a closed loop feedback control where unregulated device has an open loop control.

Example

  • Voltage regulator is a regulated output device
  • Transformer is a unregulated out device.
