RESISTOR DIVIDER OPTIONS

† Switch positions are shown with EN low (active).

‡ For most applications, SENSE should be externally connected to OUT as close as possible to the device. For other implementations, refer to

SENSE-pin connection discussion in Applications Information section.

§ 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.
