TPS7A33
SBVS169C –DECEMBER 2011–REVISED FEBRUARY 2013 www.ti.com
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated is not implied. Exposure to absolute-
maximum rated conditions for extended periods may affect device reliability.
(2) No permanent damage will occur to the part operating within this range though electrical performance is not ensured outside the
operating free-air temperature range.
