SBVS067C–JANUARY 2006–REVISED AUGUST 2006
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.

Most output voltages from 1.5V to 5.0V in 100mV increments are available on a quick-turn basis using innovative factory package-level
programming. Minimum order quantities apply; contact factory for details and availability.
For fixed 1.2V operation, tie FB to OUT.
