Capacitor Voltage Hold up (During Input Power 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?
