Hi, i’ve made a system that use a LDO to power up the nextion Screen, an MIC29300-5.0WT 3A@5V
But after some seconds, the screen power loop, the LDO became very hot and are noisy. It made frie an Bluetooth module on an other LDO (same power supply, same GND but not same 5V output) and other components crash. I’ve tryed just the LDO and the screen but no effect, still power loop.
When i test on the usb phone charger, it work without trouble… WTF…
I’ve found this topic Nextion and audio - some PSU tips, can it solve my prob ?
