I use TPS7A25 in my power circuit. And noticed some strangeness, picked up dividing resistors in feedback to get 3.3V.
According to the datasheet formula Vout = 1.24V*(1+(R1/R2)) I chose 3.3M and 2M to get 3.28 V output. But when I soldered the circuit, I got the output about 4.05V
Then check the output voltage on VB pin - it is 1.54V, which, when substituted into the formula, just gives 4.08V, which, taking into account the accuracy of the resistors, is close to the measured.
Then checked on the other two boards and the output voltage was 3.98V and 4.02V and the voltage on the VB is 1.54V
I assumed that in the datasheet a typo of 1.24V instead of 1.54V and picked up a new pair of 1.2M and 1.1M, which gave an output voltage of 3.15V (1.54*(1+(1.2/1.1))=3.22V).
