SBVS038K–SEPTEMBER 2003–REVISED SEPTEMBER 2005
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.

Additional output voltages from 1.25V to 4.3V in 100mV increments are available on a quick-turn basis using innovative factory
EEPROM programming. Minimum order quantities 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 3inch x 3inch, 2-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 3inch x 3inch, 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.
