These devices feature an integrated programmable window watchdog, over-current protection and are designed to achieve stable operation even with a low-ESR ceramic output capacitor. The output voltage can be programmed using external resistors. Low voltage tracking feature allows for a smaller input capacitor and can possibly eliminate the need of using a boost converter during cold crank conditions. The PowerOn Reset delay is fixed (250 µs typical), and can also be programmed by an external capacitor. Because of such features, these devices are well suited in power supplies for various automotive applications.

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.
