Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings define the conditions under

which the device is intended to be functional. For specifications and test conditions, see the Electrical Characteristics.

Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings define the conditions under

which the device is intended to be functional. For specifications and test conditions, see the Electrical Characteristics.

(2)

Thermal shutdown will occur if the junction temperature (TJ) exceeds 165°C. The maximum allowable power dissipation (PD) at any

ambient temperature (TA) is PD = (TJ(MAX) – TA)/θJA . This number applies to packages soldered directly onto a 3" x 3" PC board with

2oz. copper on 4 layers in still air. For a 2 layer board using 1 oz. copper in still air,

θJA = 204°C/W.

(3)

Thermal shutdown will occur if the junction temperature (TJ) exceeds 165°C. The maximum allowable power dissipation (PD) at any

ambient temperature (TA) is PD = (TJ(MAX) – TA)/θJA . This number applies to packages soldered directly onto a 1" x 0.75" PC board with

1oz. copper on 4 layers in still air.
