Raspberry pi 3B+ I2C issue

Hello Pi Users, We discovered that there is an issue with Pi 3B+ 3.3V voltage regulator. If you have a Pi3b+ and are trying to use it with an i2c shield or any other shield which usages 3.3V, you might be observing something like this The shield or hat works fine with Raspberry pi 2,3 or zero but same hat does not work with Pi3B+. The Pi3b+ wont even boot if the shield or hat is plugged in. As soon as you unplug the shield pi 3b+ will start working. The issue seems to be with Raspberry pi3B+ …

Thanks
