°C/W Note 2
Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., T_A, T_J, _JA). Exceeding the
maximum allowable power dissipation will cause the device operating junction temperature to exceed the
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.
2: The maximum allowable power dissipation at any ambient temperature is calculated using: P_(MAX) =
(T_J(MAX) – T_A) ÷ θ_JA. Exceeding the maximum allowable power dissipation will result in excessive die tem-
perature, and the regulator will go into thermal shutdown. The θ_JC of the MIC5200-x.xYS is 15°C/W and
θ_JA for the MIC5200YM is 160°C/W mounted on a PC board (see Thermal Considerations for further
details).
