°
C
2.Although power dissipation is internally limited, specifications apply only for P 
≤
 Pmax = 25 W.
3.Load and line regulation are specified at constant junction temperature. Pulse testing is required with a pulse width 
≤
 1.0 ms and a duty cycle 
≤
 5%.
4.Without a heatsink, the thermal resistance (R
JA is 65
°
C/W). With a heatsink, the effective thermal resistance can approach the specified values of
2.0
°
C/W, depending on the efficiency of the heatsink.
