Device Nomenclature

Table 9-1 Device Nomenclature(1)(2)
PRODUCTVOUT
TPS7A21xx(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 TPS7A21 family actively discharge the output when the device is disabled.
yyy is the package designator.
z is the package quantity. J is for 12000-piece reel.
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 at www.ti.com.
Output voltages from 0.8 V to 5.5 V in 50-mV increments are available. Contact the factory for details and availability.
