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 device is guaranteed to meet performance specifications within 0℃~70℃ operating temperature range
and assured by design from –40℃~85℃.
3.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.
