Table 3. Static Electrical Characteristics
Characteristics noted under conditions 3.0 V ≤ VIN ≤ 6.0 V, -40°C ≤ TA ≤ 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.

Notes
12. Section “MODES OF OPERATION”, page 15 has a detailed description of the different operating modes of the 34716
13. Design information only, this parameter is not production tested.
14. Overall output accuracy is directly affected by the accuracy of the external feedback network, 1% feedback resistors are recommended.
15. ±1% is assured at room temperature.
