Note : 1. The maximum steady state usable output current is dependent on input voltage, heat sinking, lead length of the package
and copper of PCB. The data above represent pulse test conditions with junction temperatures specified at the initial of
test.
2. Power dissipation<0.625W for TO-92, <0.5W for SOT-89.
