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.

Pulse-testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible.
Line voltage regulation is expressed here as the percentage change in output voltage per 1-V change at the input.
CADJ is connected between the ADJUST terminal and ground.
