11 Device and Documentation Support

11.1 Device Support

11.1.1 Development Support

11.1.1.1 Evaluation Modules

An evaluation module (EVM) is available to assist in the initial circuit performance evaluation using the TPS7A33. The TPS7A3301EVM-061 evaluation module (and related user's guide) can be requested at the TI website through the product folders or purchased directly from the TI eStore.

11.1.1.2 Spice Models

Computer simulation of circuit performance using SPICE is often useful when analyzing the performance of analog circuits and systems. A SPICE model for the TPS7A33 is available through the product folders under the Tools & Software tab.

11.1.2 Device Nomenclature

Table 3. Device Nomenclature(1)

PRODUCT VOUT
TPS7A3301YYYZ YYY is the package designator.
Z is the tape and reel quantity (R = 3000, T = 250).
