operating conditions for the regulator circuit. The
junction-to-ambient
minimum footprint is 100°C/W.
The maximum power dissipation must not be
exceeded for proper operation.
For example, when operating the MIC5320-MFYMT at
an input voltage of 3.3V and 150mA loads at each
output with a minimum footprint layout, the maximum
ambient operating temperature T

Therefore, a 2.8V/1.5V application with 150mA at
each output current can accept an ambient operating
