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.

TPS717 xxyyyz XX is nominal output voltage (for example, 28 = 2.8V, 285 = 2.85V, 01 = Adjustable).
YYY is package designator.
Z is package quantity.
(1) For the most current package and ordering information see the Package Option Addendum at the end of this document, or see the TI
website at www.ti.com .
(2) Output voltages from 0.9V to 5.0V 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). All voltages are with respect to GND.
