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. 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 for details.
2. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside. See Tech Brief TB379 for details.
Electrical Specifications Recommended operating conditions unless otherwise noted. V_IN = V_IN_LDO = PV_CC = 3.3V, Compensation
Capacitors = 33nF for LDO1 and LDO2. T_A = 25^oC. (Note 2)
