For example, when operating the MIC5370-MGYMT at
an input voltage of 3.6V and 150mA loads at each output
with a minimum footprint layout, the maximum ambient
operating temperature T

Therefore, a 2.8V/1.8V application with 150mA at each
output current can accept an ambient operating
temperature of 89.9°C in a 1.6mm x 1.6mm MLF
package. For a full discussion of heat sinking and
