12.1 Device Support

12.1.1 Development Support

12.1.1.1 Evaluation Modules

An evaluation module (EVM) is available to assist in the initial circuit performance evaluation using the TPS7A30. The TPS7A30-49EVM-567 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.

12.1.1.2 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 TPS7A30 is available through the product folders under the Tools & Software tab.

12.1.2 Device Nomenclature

Table 3. Ordering Information(1)

PRODUCT VOUT
TPS7A30xxyyyz XX is nominal output voltage (01 = Adjustable).(2)
YYY is package designator.
Z is package quantity.
