TPS7A24: TPS7A2401DBVR data sheet 8.2.2.2 Selecting Feedback Divider Resistors error

Part Number: TPS7A24

Please confirm the error in the data sheet of TPS7A2401DBVR.

The calculation example in "8.2.2.2 Selecting Feedback Divider Resistors" is
I think it is a calculation example of VOUT = 3.3V, so do you meet with the recognition that the following is a typographical error?
(×: wrong, 〇: correct)

× For this design example, VOUT is set to 5 V.
↓
〇 For this design example, VOUT is set to 3.3 V.


× R1 + R2 ≤ 5 MΩ.
↓
〇 R1 + R2 ≤ 3.3 MΩ.


Please answer.

    Hello, 

    There is a typological error, the calculations match Vout=3.3V as you mentioned.

    It is also correct that for Vout=5V equation 9 does provide R1 + R2 ≤ 5 MΩ, but indeed, the rest of the section uses Vout=3.3V. So all together the equations and the math are correct, except the data sheet did not continue with the original Vout=5V and ended in a Vout=3.3V scenario. 

    I will submit a datasheet review so this can be addressed properly. Thank you for the kind observation. 

    Best,
