temperature drift

This refers to the output fluctuation due to changes in the ambient temperature of the power circuit. Typically, the output at the highest and lowest temperatures specified in the specifications is measured, along with the output at room temperature. In some cases, the amount of output variation for a 1℃ change in ambient temperature is expressed as a percentage. To achieve stable output, a smaller temperature drift is desirable. Initial drift, which is the output variation from power-on until each internal component reaches continuous operating temperature, is also considered a type of temperature drift.
