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.

TPS734xxyyyz
XX is nominal output voltage (for example, 28 = 2.8V, 285 = 2.85V, 01 = Adjustable).
YYY is package designator.
Z is package quantity.

Output voltages from 1.0V to 3.6V in 50mV increments are available through the use of innovative factory EEPROM programming;
minimum order quantities may apply. Contact factory for details and availability.
Over operating temperature range (unless otherwise noted).

Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not implied.
