SGDS037A – OCTOBER 2007 – REVISED DECEMBER 2007

This family of regulators is particularly suited as a portable power supply solution due to its minimal board space

requirement and 1.8 V minimum input voltage. Being able to use two off-the-shelf AAA batteries makes system

design easier and also reduces component cost. Moreover, the solution is more efficient than if a regulator with a

higher input voltage is used.

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.

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 recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltage

values are with respect to network ground terminal.
