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_JA 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 θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications Typical Values Are Tested at 25°C and 5V Input, Maximum and Minimum Values Are Guaranteed Over 0°C to
70°C Ambient Temperature with a Supply Voltage in the Range of 4.35V to 10V, Unless Otherwise Noted.
