Recovery time

The time in a power supply circuit that represents the stability of the output in response to input changes. When the input voltage or output current is rapidly changed to the positive or negative side within a specified range, the output voltage temporarily fluctuates due to transient drop and then returns to its rated value. The time taken for this recovery is measured for both the positive and negative changes, and the longer of the two is defined as the recovery time. The smaller the recovery time, the higher the output stability, and the less susceptible it is to voltage drops caused by momentary interruptions.
