*Stresses greater than those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
these or any other conditions above those indicated in the
operation section of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods
may affect reliability.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for
which the device is functional , but do not guarantee specific performance limits. For guaranteed Specs & Test conditions, see Electrical
Characteristics section.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by Tjmax(max Junction temp), ThetaJA
(package junction to ambient thermal resistance), and TA(ambient temp). The maximum allowable power dissipation at any temperature is
Pdmax (Tjmax - TA)/ThetaJA or the number given in the Absolute Maximum Rating, whichever is lower.
Note 3: For the Ceramic 16lead gullwing, device to function properly, the “OUTPUT” and “OUTPUT/SENSE” pins must be connected on the
users printed circuit board.
