Table 1 shows junction-to-ambient thermal resistance for
the MIC5305 in the 6-pin 2mm × 2mm MLF
Substituting P
operating temperature will give the maximum operating
conditions for the regulator circuit. The junction-to-
ambient thermal resistance for the minimum footprint
(the minimum amount of copper that you can solder the
part to) is 93°C/W, from Table 1. The maximum power
dissipation must not be exceeded for proper operation.
For example, when operating the MIC5305-2.9BML at
an input voltage of 5.0V and 150mA load with a
