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 1.5 A 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 can be used as the power-pass element in precision
regulators.

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.

Maximum power dissipation is a function of T

,
θ
JA
, and T
A
. The maximum allowable power dissipation at any allowable ambient
temperature is P
D
= (T
J(max)
– T
A
)/θ
JA
. Operating at the absolute maximum T
J
of 150°C can affect reliability.
For packages with exposed thermal pads, such as QFN, PowerPAD™, or PowerFLEX,
θ
JP
is defined as the thermal resistance between
the die junction and the bottom of the exposed pad.
