Hello Wenming
What is the voltage that you use on VLDO3IN?
Are you using to VLDO1 or only the VLDO3?
Can you send me your configuration to VLDO3?, please add all registers
Can you show me your schematic?
If you have any problems sharing your scheme through the community, I recommend opening a ticket on our support page so we can talk more confidently.
I will be waiting for your response
Have a great day and best of luck.
