cause excessive die temperature, and the regulator will go into thermal shutdown.

3). All limits guaranteed at room temperature (standard typeface) and at temperature extremes (bold typeface).

4). Typical numbers are at 25°C and represent the most likely norm.

5). Current limit at 0% duty cycle.
