(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) A lower RθJC is attainable if the exposed pad is connected to a large copper ground plane.　RθJC and RθJA are values for 56-pin TSSOP without a exposed heat slug (HSL) on bottom. 　Actual thermal resistance would be better than the above values.
(3) All voltage values are with respect to the GND.
(4) The output voltage generated with regeneration current at the time of output is off states.
