Momentary Power Failure Compensation Time

When the input voltage of the power circuit is momentarily turned off/on, the maximum input voltage interruption time during which the output voltage can remain within the regulated voltage accuracy range matches the output hold time. To ensure regulated voltage, it is desirable for the momentary interruption compensation time to be long. The longer this time is, the less susceptible the system is to the effects of momentary interruptions (instantaneous voltage drops) in the input voltage.
