NOTES: 1. Tlow to Thigh = 0° to +125°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 (RθJA 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.
