Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional.

(2)

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

specifications.

(3)

Thermal resistance of TO-226 (LP) package is 60°C/W

θJC, 232°C/W θJA at still air, and 88°C/W at 400 ft/min of air. The θJA of the

LM78LXX in the 6-Bump DSBGA package is 114°C/W when mounted on a 4-Layer JEDEC test board (JESD 51-7). The

θJA of the

LM78LXX in the SOIC-8 (D) package is 180°C/W in still air. The maximum junction temperature shall not exceed 125°C on electrical

parameters.
