Hello,

Can you give the values of internal feedback resistors (RFBT, RFBB) for 3.3V fixed output voltage reference?

It is not written in the datasheet.

Regards,

Fabien

Hello Fabian,

I will need to follow up as a lost access to some software which contains this information.

If I remember correctly, RFBT is 500kOhm to 900kOhm and RFBB is based on voltage divider principle, with output being equal to internal fb voltage of 1V.

Following up, below are the values

* 1214.5K is for 5V

* 698.5k is for 3.3V

VREF = 1

RFBB = {{RFBT*VREF} / {Vout-VREF}}
