CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTE:
1. θ_JC is measured with the component mounted on a typical application PCB. A separate θ_JC value is provided for each of the three exposed die
pads (#69, 70, 71). Each value should be used in combination with the power dissipated by only the individual die mounted on that pad.
Electrical Specifications Recommended Operating Conditions, Unless Otherwise Noted. Refer to Figures 1, 2 and 3
