I'm designing a circuit using a 328p.
I've specified already the .01uF decoupling capacitors on the Vcc and GND pairs for the device.
I had someone knowledgeable in electronics recommend an added reservoir capacitor for the circuit.
I'm aware that the decoupling caps and the reservoir cap essentially provide voltage smoothing.
I'm operating at 5V, and the total current draw on the 5V line is going to be about 50 mA.
I've looked at the following website and tried their calculator, but I'm unsure about how long the charge time would be.
I'm looking for guidance on helping to size the reservoir capacitor I've mentioned.
