Note 3. Assumes the use of a heat sink having a thermal resistance of 1°C/W and no insulator with
an ambient temperature of 25°C. Because the output limiting circuitry has a negative temper-
ature coefficient, the maximum output power delivered to a 4Ω load may be slightly reduced
when the tab temperature exceeds 55°C.
