Notes: 1. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical
Specifications do not apply when operating the device outside of its rated Operating Conditions.
2. The maximum allowable power dissipation at any ambient temperature is PMAX = (125-TA)/ θJA, where 125
is the maximum junction temperature for operation, TA is the ambient temperature, and θJA is the
junction to ambient thermal resistance. If this dissipation is exceeded, the die temperature will rise above
125C and the electrical specifications do not apply. If the die temperature rises above 150C, the
LM2937 will go into thermal shutdown.
