Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2: See circuit in Typical Applications. To ensure constant junction temperature, low duty cycle pulse testing is used.
Note 3: All limits are guaranteed for T
Note 4: The maximum power dissipation is a function of maximum junction temperature T
maximum allowable power dissipation at any ambient temperature is P
150°C and the LM2931 will go into thermal shutdown. For the LM2931 in the TO-92 package, θ

If the TO-263 package is used, the thermal resistance can be reduced by increasing the P.C. board copper area thermally connected to the package: Using 0.5
