Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Absolute maximum input to output differential voltage cannot be
achieved with all combinations of rated IN pin and OUT pin voltages. With
the IN pin at 20V, the OUT pin may not be pulled below 0V. The total
measured voltage from in to out can not exceed ±20V.
Note 3: The LT1962 regulators are tested and specified under pulse load
conditions such that TJ ≈ TA. The LT1962 is 100% tested at TA = 25°C.
Performance at – 40°C and 125°C is assured by design, characterization
and correlation with statistical process controls.
Note 4: The LT1962 (adjustable version) is tested and specified for these
conditions with the ADJ pin connected to the OUT pin.
