Adafruit 16ch Servo Hat Mosfet Baking Hot


I bought an ADA2327 from you a while ago , and only recently starting using it. When I connect it along with a 5V external PSU (-ve sheath), the regulator directly behind the 5V socket starts ticking with heat and burns to the touch. I’ve disconnected it promptly to avoid damage.

I noticed a thread an Adafruit’s forum’s which seems to exhibit the same problem.

Can you help?
