Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 6:
To satisfy minimum input voltage requirements, the LT3062 may cause permanent damage to the device. Exposure to any Absolute adjustable version is tested and specified for these conditions with an Maximum Rating condition for extended periods may affect device external resistor divider (bottom 60k, top 230k) for an output voltage of reliability and lifetime. 2.9V. The external resistor divider adds 10µA of DC load on the output.

Absolute maximum input to output differential voltage is not The external current is not factored into GND pin current. achievable with all combinations of rated IN pin and OUT pin voltages.
Note 7:
Dropout voltage is the minimum input-to-output voltage With the IN pin at 50V, the OUT pin may not be pulled below 0V. The total differential needed to maintain regulation at a specified output current. In measured voltage from IN to OUT must not exceed ±50V. If OUT is above dropout, the output voltage equals: (VIN – VDROPOUT). ground, do not pull IN more than 40V below OUT.

Reverse output current is tested with the IN pin grounded and the range if operating at the maximum input voltage. Limit the input-to-output OUT pin forced to the specified voltage. This current flows into the OUT voltage differential if operating at maximum output current.
