(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) This pin is not specified to have an external voltage applied.

(3) 18 V or V_BIAS + 0.3 V whichever is lower

(4) The maximum current sink is limited to 1 mA when V_PGOOD>V_BIAS.

(5) This pin has an internal max voltage clamp which can handle up to 1.6 mA.

(6) High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C.
