The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C.
Note 3: VON/OFF = 0.4V for –55°C ≤ TA ≤ 100°C and VON/OFF = 0.2V for
100°C ≤ TA ≤ 125°C. Does not apply to LT1039A-16 part.
Note 4: For TA ≥ 100°C leakage current is 350A max.
Note 5: Bias pin open on 18-pin version.
