I am trying to make a power supply for ESP32 using LNK306DN with one diode rectifier 1N4007.
I want the output power suppy is 6V then I use LM1117 to get 3.3V before connect to ESP32.
But I have a problem, the LNK306 always restarts.
I measured the output drop to 4V then returned to 6V.
I think this is lacking current for ESP32.
I tried with another power supply with a voltage of 3.3V 300mA can boot.
And I have tried replacing EC1 & EC2 with 2.2uF/400V but the results still same.
Is there something wrong with my circuit, please advise.
