6.1 Absolute Maximum Ratings

over operating free-air temperature range unless otherwise noted(1)(2)
MIN MAX UNIT
Voltage range on IN, OUT, EN, ILIM, FAULT –0.3 7 V
Voltage range from IN to OUT –7 7 V
IO Continuous output current Internally Limited
Continuous FAULT sink current 25 mA
ILIM source current 1 mA
TJ Maximum junction temperature –40 150 °C
Tstg Storage temperature –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Voltages are referenced to GND unless otherwise noted.
