Notes

13.

For 3.3 V VDD devices, the drop-out voltage test condition leads to a VSUP below the min VSUP threshold (4.0 V). As a result, the dropout

voltage parameter cannot be specified.

14.

The regulator is stable without an external capacitor. Usage of an external capacitor is recommended for AC performance.

Table 4. Static Electrical Characteristics (continued)

Characteristics noted under conditions 5.5 V

≤ VSUP ≤ 28 V, -40 °C ≤ TA ≤ 125 °C, unless otherwise noted. Typical values

noted reflect the approximate parameter means at TA = 25 °C under nominal conditions, unless otherwise noted.
