Substituting P D for P D(max) and solving for the ambient
operating temperature will give the maximum operating
conditions for the regulator circuit.
The maximum power dissipation must not be exceeded
for proper operation.
For example, when operating the MIC94300YMT at an
input voltage of 2.75V and 200mA load with a minimum
footprint layout, the maximum ambient operating
temperature T A can be determined as follows:
0.05W = (125 ° C ? T A )/(173 ° C/W)
T A = 116 ° C
Therefore the maximum ambient operating temperature
of 116°C is allowed in a 1.2mm x 1.6mm MLF ? package.
For a full discussion of heat sinking and thermal effects
on voltage regulators, refer to the “Regulator Thermals”
section of Micrel’s Designing with Low-Dropout Voltage
