STM32H563 maximum current consumption of AD converter(RUN mode)

I searched about STM32H563 maximum current consumption of AD converter when run mode on datasheet and reference manual.

I could't find AD converter's maximum current consumpsion on datasheet and reference manual.

I want to consider external LDO for VDDA by AD converter's maximum current consumption.

Please advise for me.

see ds :

Any LDO will have more than 1mA output...even the smallest have 50mA or more max. output current.

>I want to consider external LDO for VDDA

Why ? ultra low noise LDO ? H563 has 12b ADC , so not much to gain , if VDD has LDO anyway.

Thank you for your advice.

I was searching on keyword "current consumption".

VDD need many current by logic circuit around H563,
so, generate from switching regulator circuit.

therefore, I considering LDO for VDDA.
