8.1.1 Device Nomenclature

PRODUCT(1)(2)VOUT
TPS7A21xx(x)(C)PQ(W)yyyzQ1xx(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 = 2.8V; 125 = 1.25V).

C (when present) indicates an alternate pin configuration.

P indicates an active output discharge feature. All variants of the TPS7A21 actively discharge the output when the device is disabled.

Q indicates that this device is a Grade-1 device in accordance with the AEC-Q100 standard.

W (when present) indicates the package has wettable flanks.

yyy is the package designator.

z is the package quantity. R is for a 3,000 piece reel.

Q1 indicates that this is an automotive grade (AEC-Q100) device.

(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 at www.ti.com.
(2) Output voltages from 0.8V to 5.5V in 50mV increments are available. Contact the factory for details and availability.
