Momentary power failure compensation time

When the input voltage of a power supply circuit is instantaneously turned off/on, the maximum input voltage interruption time during which the output voltage can maintain the constant voltage accuracy range, and it matches the output hold-up time. To ensure a constant voltage, a longer momentary interruption compensation time is desirable. The longer this time, the less susceptible it is to momentary interruptions (instantaneous voltage drops) in the input voltage.
