Note:1. Absolute maximum ratings are stress ratings only and functional device operation is not implied. The device

could be damaged beyond Absolute maximum ratings.

2. The maximum steady state usable output current are dependent on input voltage, heat sinking, lead length

of the package and copper pattern of PCB. The data are showed as electrical characteristics table

represents pulse test conditions with junction temperatures specified at the initiation of test.
