When the circuit is not connected to the supercapacitor, the output is normal. After the circuit is connected to the supercapacitor (5V 0.33f), the output of the circuit becomes weak after one minute, and then there is no output. I would like to ask what is the reason for this? The same is true when I plug in small capacitors or electrolytic capacitors. Is it circuit connection problem or capacitance selection error? My supercapacitor is connected to the Vin port and connected to the ground.
