... At this point important to ensure that the die temperature does not exceed 125°C. Power dissipation in the regulator is calculated as follows The MIC5231 consumes only 0.65uA over load and does not need to consider that contribution in the power dissipation equation, therefore the equation is simplified The MIC5231, in the IttyBitty SOT23-5 package, has a thermal resistance, junction-to-ambient, of 235° ...

... D(max 170mW D(max) Therefore, the device can only dissipate 170mW maximum. If the MIC5231 is powered off of a 12V source and the output voltage is 3.3V, the maximum output current can be calcu- lated (Vin - Vout)·Iout D 170mW = (12V - 3.3V)·Iout Iout = 170mW/8 ...
