description/ordering information
This series of fixed-voltage integrated-circuit voltage regulators is designed for a wide range of applications.
These applications include on-card regulation for elimination of noise and distribution problems associated with
single-point regulation. Each of these regulators can deliver up to 500 mA of output current. The internal
current-limiting and thermal-shutdown features of these regulators essentially make them immune to overload.
In addition to use as fixed-voltage regulators, these devices can be used with external components to obtain
adjustable output voltages and currents and also as the power-pass element in precision regulators.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

*For packages with exposed thermal pads, such as QFN, PowerPAD, and PowerFLEX,
JP is defined as the thermal resistance between the die
junction and the bottom of the exposed pad.
NOTE 1: Maximum power dissipation is a function of TJ(max),
JA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) - TA)/
JA. Operating at the absolute maximum TJ of 150
C can affect reliability.
