Your self-developed electronic control module needs 200ms to safely shut down and write back data into nonvolatile memory. How big would the power regulator output capacitance need to be at least to do that in the event of a unexpected shutdown (GLV Master switch turn-off), given that: + The device needs a constant current of 120mA + The regulated voltage is 5V + The CPU will brown-out at 3.8V + There is no reverse-flow back into the supply
