Static load fluctuation

In power circuits and similar applications, this refers to the variation in output voltage when the input voltage and other conditions are at their rated values, and the output current is gradually changed within a specified range (usually within the rated range). It is one of the indicators of the stability of a power circuit, and the smaller the static load regulation, the higher the stability against long-term gradual load changes. It is useful for estimating the stability of the output voltage in applications where the load changes gradually.
