Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device by be impaired.

Note 2: VON/OFF = 5V for LT1039M grade devices.

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 LT1039-16 part.

Note 4: For TA ≥ 100°C, leakage current is 350µA max.

Note 5: For TA ≤ –25°C, output source current is 0.4mA.
