Electrical Characteristics
Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.
Note 2: 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 temperature coefficient, the maximum output power delivered to a 4 load may be slightly reduced when the tab temperature exceeds 55˚C.
