Notes:
9. The maximum steady-state usable output current and input voltage are very dependent on the heat sinking and/or
lead length of the package. The data above represents pulse test conditions with junction temperature as indicated
at the initiation of tests.
10. Power dissipation P_D ≤ 0.75 W.
