The datasheet indicates the Viso voltage is...1.23V*(R1+R2)/R1.
What is the typical and maximum tolerance of the internal 1.23V reference voltage ?
Tony: Unfortunately, we don't have a specification for the 1.23V reference voltage. I looked at some data that shows that at room temperature and 5V output, Viso output could vary from about 4.75 to 5.25V.
