11.1 Device Support

11.1.1 Development Support Evaluation Module

An evaluation module (EVM) is available to assist in the initial circuit performance evaluation using the TPS715A. The TPS715AXXEVM-065 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. 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 TPS715A is available through the product folders under Tools & Software.

11.1.2 Device Nomenclature

Table 3. Device Nomenclature(1)

TPS715Axxyyyz xx is nominal output voltage (for example 33 = 3.3V, 01 = adjustable)
yyy is package designator
z is package quantity

11.5 Electrostatic Discharge Caution


This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
