Thermal Resistance
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 junction-to-
ambient thermal resistance for the minimum footprint is
235
°
C/W. The maximum power dissipation must not be
exceeded for proper operation.
For example, when operating the MIC5265-2.8YD5 at an
input voltage of 5.0V at 150mA with a minimum footprint
layout, the maximum ambient operating temperature T

can be determined as follows:

Therefore, a 2.8V application at 150mA of output current
can accept an ambient operating temperature of 47°C in
a SOT-23-5 package. For a full discussion of heat
sinking and thermal effects on voltage regulators, refer
