Case Temperature*: The temperature measurement was taken at the hottest point on the MIC61300 case mounted on a 2.25 square inch PCB at an
ambient temperature of 25°C; see “Thermal Measurement” section. Actual results will depend upon the size of the PCB, ambient temperature and
proximity to other heat emitting components.
