To determine the maximum ambient operating
temperature of the package, use the junction-to-
ambient thermal resistance of the device and the
following basic equation:

The maximum power dissipation must not be
exceeded for proper operation.
For example, when operating the MIC5301-2.8YML at
an input voltage of 5V and 150mA load with a
minimum footprint layout, the maximum ambient
operating temperature T
follows:
Therefore, a 2.8V application with 150mA of output
current can accept an ambient operating temperature
of 92°C in a 1.6mm x 1.6mm MLF
