Customer designed TLV803M on their project.
However, customer suffered the issue with different reset voltage for different manufactory side from China and Tailand.
Would you please help review schematic and see any concern for this schematic?
here is schematic.
One thing I found is there is no pull up resistor. One pin connect to scalar GPIO(audio-SD PIN )and scalar inside is push pull structure.
Will that impact this TLV803M reset pin output behavior?

Thanks for help!
