I'm using an ESP-32 to switch an AC load. My PCB has onboard

• 12 V 3 A - From wall mount adapter
• 5 V 800 mA - From the step-down regulator
• 3.3 V - from ESP not being used anywhere.

I'm getting 5V at pin 5 of the relay but only drops to 4.9 V when triggered.

My relay is JQC-3FC(T73)DC05V. Currently, I have not connected anything to the output of the relay.

I've also shorted R8, still no avail.
