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