The change in output voltage when the load on the output is changed.

The percent change in output voltage as the load is changed from minimum to maximum, at constant line and constant temperature. The load change may be specified for other than no load to full load, e.g., 30% to full load

The change in a converter's output voltage due to a change in the load current, usually expressed in percent at two or more specified load levels.

A change of output voltage that occurs as the result of a change in an output's load (usually from no-load to a full load). This is expressed by a percentage of nominal DC output voltage.

Load regulation means that the power supply will provide a constant voltage as the current drawn from the load goes up and down. This has a plumbing analogy. During the Super Bowl, when a lot of beverages are being consumed in front of the TV and no one wants to miss the action, city water pressure is at a constant. During the commercials, when the football fans are at liberty to engage in plumbing activities, the city water pressure drops precipitously, sometimes triggering water-failure alarms in industry. We power supply designers would say that the city water pressure does not have good load regulation. Again, inexpensive transformer-based wall mount power supplies are designed to give a certain voltage at a certain current draw. When the current changes voltage changes, how much depends on the design of the transformer. Switching supplies are fully regulated, so have good load regulation, as do linear regulated supplies.

The change in output voltage expressed as a percent for a given step change in load current. Initial and final current values and the rates of change must be specified. The rate of change shall be expressed as current/unit of time, e.g., 20 amperes per microsecond. The dynamic regulation is expressed as a +/- percent for a worst case peak-to-peak deviation for DC supplies, and worst case rms deviation for AC supplies.

The change in output voltage, in percentage, as the load is varied from minimum to maximum, all other parameters held constant.

The change in a converterÕs output voltage resulting from a predefined change in the load current, expressed as a percentage of the output voltage.

1) Static: The change in output voltage as the load is changed from the specified minimum to maximum and maximum to minimum, with all other factors held constant. 2) Dynamic: The change in output voltage expressed as a percentage for a given step change in load current.

Change in output voltage due to a varying load. Expressed as a percent of the normal output voltage, a power supply with tight load regulation delivers optimum voltages regardless of system configuration. This is tested by measuring the difference in output voltage when applying a light load and a heavy load.

The change in value of DC output voltage resulting from a change in load resistance from open circuit to a value that yields maximum rated output current, or from full load to open circuit.

The percent change in output voltage for a given change in load current. A rating that indicates the change in regulator output voltage that will occur per unit of change in load current.

The ability of a voltage regulator to maintain a constant output voltage under varying load currents.
