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. 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 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.
