... MIC5219 Notes: 1. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifi cations do not apply when operating the device outside of its operating ratings. The maximum allowable power dissipation is a function of the maximum junction temperature, T the junction-to-ambient thermal resistance, θ ...

... For example, if the regulator is operating normally at 50mA, but for 12.5% of the time it operates at 500mA output, the total power dissipation of the part can be easily determined. First, calculate the power dissipation of the device at 50mA. We will use the MIC5219-3.3BM5 with 5V input voltage as our example However, this is continuous power dissipation, the actual on-time for the device at 50mA is (100%-12 ...
