ELECTRICAL CHARACTERISTICS
STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics (continued)
Characteristics noted under conditions -40°C ≤ TJ ≤ 85°C unless otherwise noted. Input voltages 2.8 V ≤ VIN ≤ 13.5 V. Typical
values noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.
