Although power dissipation is internally limited, specifications apply only for P ≤ 30W. (2) Load and line regulation are specified at constant junction temperature. Pulse testing is required with a pulse width ≤ 1 ms and a duty cycle ≤ 5%. (3) Without a heat sink, the thermal resistance of the TO-3 package is about 35°C/W. With a heat sink, the effective thermal resistance can only approach the specified values of 2°C/W, depending on the efficiency of the heat sink. 4 Submit Documentation Feedback Copyright © 2004, Texas Instruments Incorporated Product Folder Links: LM123 LM323-N LM323A |
