PRODUCTVOUT
TPS7A02xx(x)PyyyzXX(X) is the nominal output voltage. For output voltages with a resolution of 100 mV, two digits are used in the ordering number; otherwise, three digits are used (for example, 28 = 2.8 V; 125 = 1.25 V).
P indicates an active output discharge feature. All members of the TPS7A02 family actively discharge the output when the device is disabled.
YYY is the package designator.
Z is the package quantity. R is for reel (3000 pieces), T is for tape (250 pieces).
(1) For the most current package and ordering information see the Package Option Addendum at the end of this document, or visit the device product folder on www.ti.com.
(2) Output voltages from 1.0 V to 3.3 V in 50-mV increments are available. Contact the factory for details and availability.
