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.

Dissipation rating tables and figures are provided for maintenance of junction temperature at or below
absolute maximum temperature of 150°C. For guidelines on maintaining junction temperature within
recommended operating range, see the Thermal Information section.
