I want to understand how long a capacitor can provide the stable voltage for a given load current, in the event of an input voltage interruption?
Suppose, I have a single 100nF input capacitor at my 12V. Across the capacitor, I have a load of 50mA. My stable input voltage is 12V.
Suppose, the 12V drops to 0V for some, say 100us, and then comes back up to stable 12V. Will that 100nF capacitor be able to provide the stable 12V with 50mA to the load during the momentary power interruption? If not, how long will it provide the stable 12V maintaining the same load current?
Is there any formula or a way to figure out the minimum capacitance needed to support this requirement? Or how long the capacitor can provide the stable 12V with the same 50mA Load?
