TLV320DAC3203: TLV320DAC3203 LDOIN range with internal A-LDO enabled

Hi Ti,

As per we are using TLV320DAC3203 with internally A-LDO enabled to have 1.8V at AVDD without any external regulator on this pin. Our LDOIN and IOVDD is at 3.1V and we have DVDD via separate 1.8V regulator. I need to know if my understanding is correct that minimum voltage at LDOIN is 1.9V to have A-LDO enabled, please confirm?

Here is how I have added the whole circuit for TLV320DAC3203. 

Kind regards,

Mat
