... The MIC5231 also features a control pin which allows the regulator to be shut down when not required. Its shutdown- state draws zero current, benefitting battery-powered appli- cations. The MIC5231 is available in fixed output voltages of 2.75V, 3.0V, 3.3V and 5V in the small SOT-23-5 IttyBitty™ package. Contact Micrel for other voltage options. Typical Application IttyBitty is a trademark of Micrel, Inc ...

... 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 ...
