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
11. Section “MODES OF OPERATION”, page 16 has a detailed description of the different operating modes of the 34717
12. Design information only, this parameter is not production tested.
13. This is directly affected by the accuracy of the external feedback network, 1% feedback resistors are recommended.
