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)

If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/Distributors for availability and

specifications.

(3)

Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by TJMAX

(maximum junction temperature), RθJA (junction to ambient thermal resistance) and TA (ambient temperature). The maximum power

dissipation at any temperature is: PDissMAX = (TJMAX – TA) / RθJA up to the value listed in theAbsolute Maximum Ratings. RθJA for SOT-23

is 164.1°C/W, TJMAX = 125°C.
