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.
NOTES:
1. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See
Tech Brief TB379.
2. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications
Typical Values Are Tested at VIN = 5V and the Ambient Temperature at 25°C. All Maximum and Minimum
Values Are Guaranteed Under the Recommended Operating Supply Voltage Range and Ambient Temperature
Range, Unless Otherwise Noted.
