TJ(MAX) = 125°C, the maximum junction temperature of  
the die.  
Power Good (PGOOD)  
The Power Good (PGOOD) pin is an open drain output  
that goes low when the output voltage (fixed version)  
drops below the PGOOD threshold voltage.  
θJA thermal resistance = 90°C/W.  
Table 1 shows junction-to-ambient thermal resistance for  
the MIC47050 in the MLF® or Thin MLF® package.  
The pull-up resistor value should be large enough to  
guarantee a proper “low” voltage when the PGOOD pin  
pulls low. The PGOOD low voltage is typically 0.1V at  
250µA current.  
recommended when pulling up to 3.3V bias.

Thermal Shutdown  
Table 1. Thermal Resistance  
The MIC47050 has an internal over-temperature  
protection feature. This feature is for protection only.  
The device should never be intentionally operated near  
this temperature as this may reduce long term reliability.  
The device will turn off when the over-temperature  
threshold is exceeded. A 20°C hysteresis is built in to  
allow the device to cool before turning back on.  
Substituting PD for PD(max) and solving for the ambient  
operating temperature will give the maximum operating  
conditions for the regulator circuit. The junction-to-  
ambient thermal resistance for the minimum footprint is  
90°C/W. The maximum power dissipation must not be  
exceeded for proper operation. For example, when  
operating the MIC47050-1.2YML at an input voltage of  
1.8V and a 0.5A load with a minimum footprint layout,  
the maximum ambient operating temperature TA can be  
determined as follows:  
Thermal Considerations  
The MIC47050 is designed to provide 0.5A of continuous  
current in a very small package. Maximum ambient  
operating temperature can be calculated based on the  
output current and the voltage drop across the part.  
Given that the input voltage is 1.8V, the output voltage is  
1.2V and the output current is 0.5A. The actual power  
dissipation of the regulator circuit can be determined  
using the equation:

Therefore, a 1.2V application with 0.5A of output current  
can accept an ambient operating temperature of 98°C in  
a 2mm x 2mm MLF® or Thin MLF® package.  
Because this device is CMOS, the ground current is  
insignificant for power dissipation and can be ignored for  
this calculation.  
Thermal Measurements  
Measuring the IC’s case temperature is recommended to  
insure it is within its operating limits. Although this might  
seem like a very elementary task, it is easy to get  
erroneous results. The most common mistake is to use  
the standard thermal couple that comes with a thermal  
meter. This thermal couple wire gauge is large, typically  
22 gauge, and behaves like a heatsink, resulting in a  
lower case measurement.

To determine the maximum ambient operating  
temperature of the package, use the junction-to-ambient  
thermal resistance of the device and the following basic  
equation:  
Two methods of temperature measurement are using a  
smaller thermal couple wire or an infrared thermometer.  
If a thermal couple wire is used, it must be constructed  
of 36 gauge wire or higher (smaller wire size) to  
minimize the wire heat-sinking effect.
