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. All voltages are with respect to GND.
2. 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.
3. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside. See Tech Brief TB379.
Electrical Specifications V_IN = +3.3V, Compensation Capacitor = 33nF, T_A = 25°C, Unless Otherwise Noted.
