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.
An output voltage droop can be programmed to improve the transient window and reduce size of the output filter.
Other features include a single voltage operation, a true differential sense amplifier, a programmable current
limit, soft-start, and a power good indicator.
