Substituting PD for PD(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 90°C/W.

The maximum power dissipation must not be

exceeded for proper operation.

For example, when operating the MIC5330-MFYML at

an input voltage of 3.3V and 300mA loads at each

output with a minimum footprint layout, the maximum

ambient operating temperature TA can be determined

as follows:

0.99W = (125°C – TA)/(90°C/W)

TA=62.9°C

Therefore, a 2.8V/1.5V application with 300mA at

each output current can accept an ambient operating

temperature of 62.9°C in a 2mm x 2mm 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 Regulators

handbook. This
