Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
The absolute maximum positive supply voltage (60V) must be of limited duration (≤100ms) and duty cycle (≤1%). The maximum continuous
supply voltage is 30V.
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 allow-
able power dissipation will result in excessive die termperature, and the regulator will go into thermal shutdown. The θ_JA of the MIC5236-x.
xBM (all versions) is 63°C/W, and the MIC5236-x.xBMM (all versions) is 80°C/W, mounted on a PC board (see “Thermal Characteristics” for
further details).
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total temperature range.
Regulation is measured at constant junction temperature using pulse testing with a low duty-cycle. Changes in output voltage due to heating
effects are covered by the specification for thermal regulation.
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1.0V
differential.
