Setting 30h is not recommended for production use unless an external VDD5 voltage is provided because the 3.9-V LDO setting can result in a VDD5 voltage less than the VDD5 undervoltage lockout required to enable conversion and can result in the TPSM8D6C24 device being unable to enable conversion without an external VDD5 voltage.
