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 represents pulse test conditions with

junction temperatures specified at the initiation of test.

Note 2: Power dissipation<0.5W
