Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Pd > (V_IN-V_OUT)×I_OUT.
3. The power dissipation measured with the test board condition is listed as reference data.
