Case Temperature*:
The temperature measurement was taken at the hottest point on the MIC371xx that was 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.
