ADR5045 for voltage divider as shunt regulator

Hi

 

I know that i can use a voltage shunt regulator for offset voltage (bias, subtract), e.g. 5V.

 

Can i use also the ADR5045BKSZ-REEL7 ?

I haven an STM32 with 0-3.3 Input. My calculations says that the total current is betwwen 75uA (6V input, 0.3V on ADC) and 825uA (16V, 3.5V on ADC).

Ist this schema correct?

 

Thank you very much for every input

 

Regards

Andy
