Note 1.

Exceeding the absolute maximum rating may damage the device.

Note 2.

The device is not guaranteed to function outside its operating rating.

Note 3:

The absolute maximum positive supply voltage (60V) must be of limited duration (

≤100ms) and duty cycle (≤1%). The maximum continuous

supply voltage is 30V.

Note 4:

The maximum allowable power dissipation of any T

allowable power dissipation will result in excessive die termperature, and the regulator will go into thermal shutdown. The

θ

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 Charac-

teristics” for further details).

Note 5.

Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.

Note 6:

Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total temperature range.

Note 7:

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.

Note 8:

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.
