STATIC ELECTRICAL CHARACTERISTICS (continued)
Characteristics noted under conditions 9.0 V ≤ V_PWR ≤ 16 V, -40°C ≤ T_J = T_A ≤ 125°C, using the typical application circuit (see
Figure 8) unless otherwise noted. Typical values noted reflect the approximate parameter mean at T_A = 25°C under nominal
conditions unless otherwise noted.
