Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
The maximum allowable power dissipation of any T_A (ambient temperature) is P_D(max) = (T_J(max)–T_A)/θ_JA. Exceeding the maximum allowable
power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. The θ_JA of the MIC5254-SJBMM is
200°C/W on a PC board (see “Thermal Considerations” section for further details).
