Hi, I need to use this regulator in a design.
I noticed that the formula in the datasheet is reversed compared to all other regulators working with internal reference:
pag. 10:

Vout = Vref x (1 + (R1/R2))
while for LM317 it is the opposite
Vout = Vref x (1 + (R2/R1))
where R1 is the upper resistor in the totem.
I wonder if this is a mistake or not. Any idea?
