Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the

Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect

device reliability.

1. The maximum power dissipation of this device is internally limited by thermal shutdown circuitry. To achieve a power dissipation of 3.0 watts,

a case−to−ambient thermal resistance of 25C/W must be provided. This will typically require dedicated heatsinking ability of the printed

circuit board. For more details, please see the Typical Thermal Characteristics section.

2. Operating Characteristics are over Standard Operating Conditions unless otherwise specified.

impedance be kept below 0.15 W to ensure the switching disturbance remains below the hysteresis during select/deselect transitions.

4. Ground pin current consists of controller current (0.2 mA) and regulator current when selected.
