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., TA, TJ, 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 TA (ambient temperature) is PD(max) = (TJ(max) – TA)/JA.

Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the reg-

ulator will go into thermal shutdown. The JA of the MIC5205-xxYM5 (all versions) is 220°C/W mounted on

a PC board.
