Thermal Considerations
Part I. Layout
The MIC5202 (8-pin SOIC package) has the thermal
characteristics shown in Table 1 , when mounted on a
single-layer copper-clad printed circuit board.

Part II. Nominal Power Dissipation and Die
Temperature
At 25°C ambient temperature, the MIC5202 operates
reliably at up to 625mW when mounted in the “worst case”
manner described in Part I. Layout . At an ambient
temperature of 55°C, the device can safely dissipate
440mW. These power levels are equivalent to a die
temperature of 125°C, which corresponds to the
recommended maximum temperature for non-military

120°C/W
grade silicon integrated circuits.
Multi-layer boards with a dedicated ground plane, wide
traces, and large supply bus lines provide better thermal
conductivity.
The “worst case” value of 160°C/W assumes no ground
plane, minimum trace widths, and a FR4 material board.
