Recovery time

In a power supply circuit, the time that represents the stability of the output in response to input changes. When the input voltage or output current is abruptly changed to the positive or negative side within a specified range, the time it takes for the output voltage to return to the rated value after transient reduction is measured for each case. The longer of the two times—positive or negative—is called the recovery time. The smaller the recovery time, the higher the output stability and the less susceptible it is to the influence of voltage drops caused by momentary interruptions.
