SBVS037I–AUGUST 2003–REVISED MAY 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.

.
Output voltages from 1.2V to 4.5V in 50mV increments are available through the use of innovative factory EEPROM programming;
minimum order quantities may apply. Contact factory for details and availability.
For fixed 1.2V operation, tie FB to OUT.

Stresses beyond those listed under
absolute maximum ratings
may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under the Electrical Characteristics
is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.

The JEDEC Low-K (1s) board design used to derive this data was a 3 inch x 3 inch, two-layer board with 2-ounce copper traces on top
of the board.
The JEDEC High-K (2s2p) board design used to derive this data was a 3 inch x 3 inch, multilayer board with 1-ounce internal power and
ground planes and 2-ounce copper traces on the top and bottom of the board.
Based on preliminary thermal simulations.
