(1) 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.
(2) Maximum power dissipation is a function of T
J
(max), θ

, and T
A
. The maximum allowable power dissipation at any allowable ambient
temperature is P

techniques must be used that maintain the junction temperature as close to the ambient temperature as possible. All characteristics are
measured with a 0.1-μF capacitor across the input and a 1-μF capacitor across the output.
(2) Input voltage regulation is expressed here as the percentage change in output voltage per 1-V change at the input.
