Momentary power failure compensation time

When the input voltage of the power supply circuit is momentarily turned off/on, the maximum input voltage interruption time during which the output voltage can maintain the constant voltage accuracy range matches the output hold time. For ensuring constant voltage, it is desirable for the momentary interruption compensation time to be long. The longer this time, the less susceptible it is to the effects of momentary voltage drops (instantaneous voltage dips) in the input voltage.
