    Hey Jimmy,

    It would be good to reduce the feedback divider values to avoid the inaccuracy in LDO output when the divider current becomes comparable to the FB pin leakage.

    It is expected to R1 + R2 < 5 Mohm

    This is discussed in details in section 9.2.2.2 Selecting Feedback Divider Resistors of the datasheet.

    As mentioned for 5V output, R1 can be 3.64Mohm and R2 can be 1.18Mohm.

    Regards,

    Rohit
