Notes
15.
Design information only, this parameter is not production tested.
16.
Overall output accuracy is directly affected by the accuracy of the external feedback network, 1% feedback resistors are recommended
17.
±1% is assured at room temperature
18.
The 1% output voltage regulation is only guaranteed for a common mode voltage range greater than or equal to 0.7V

IN ≤ 6.0 V, -40°C ≤ T
A ≤ 85°C, GND = 0 V, unless otherwise noted. Typical
values noted reflect the approximate parameter means at TA = 25°C under nominal conditions, unless otherwise noted.
