Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply

when operating the device outside of the limits set forth under the operating ratings which specify the intended range of operating

conditions.

(2)

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

specifications.

(3)

The maximum power dissipation which can be safely dissipated for any application is a function of the maximum junction temperature,

TJ(MAX) = 125°C, the junction-to-ambient thermal resistance for the SOT-23 package, RθJ-A = 210°C/W, and the ambient temperature,

TA. The maximum allowable power dissipation at any ambient temperature for designs using this device can be calculated using the

formula:

If power dissipation exceeds the maximum specified above, the internal thermal protection

circuitry protects the device by reducing the output voltage as required to maintain a safe junction temperature.
