Note 1: 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 above represent pulse test conditions with junction

temperatures specified at the initiation of test.

Note 2: Power dissipation<0.5W
