Pin Functions
DESCRIPTION
The device enable pin.
The unregulated input voltage pin
Ground
The regulated output voltage pin
The supply for the internal control and reference circuitry
The TAB is a thermal connection that is physically attached to the backside of the die, and is
used as a thermal heat-sink connection. See the Application and Implementation section for
details

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) If Military/Aerospace specified devices are required, contact the TI Sales Office/ Distributors for availability and specifications.
(3) Device power dissipation must be de-rated based on device power dissipation (T_D), ambient temperature (T_A), and package junction to
ambient thermal resistance (R_θJA). Additional heat-sinking may be required to ensure that the device junction temperature (T_J) does not
exceed the maximum operating rating. See Application and Implementation for details.
