... MOSFET’s body diode. While this effect can be used to advantage when large bypass capacitors are placed on MIC2004/2014’s’s output, it can not be relied upon to fully or reliably discharge the load capacitance, because discharging depends upon the characteristics of the circuitry at VIN ...

... If resumed operation results in reheating of the die, another shutdown MIC2004/2014 will continue cycling between ON and OFF states until the offending load has been removed. Depending on PCB layout, package type, ambient temperature, etc., hundreds of milliseconds may elapse from the incidence of a fault to the output MOSFET being shut off ...

When measuring important to bear this voltage OUT dependence in mind, otherwise the measurement data may appear to indicate a problem when none really exists. This voltage dependence is illustrated in Figures 4 and 5 ...

... I OUT 0 Supply Filtering A 0.1µF to 1µF bypass capacitor positioned close to the V and GND pins of MIC2004/2014 is both good design IN practice MIC2004/2014. This will control supply transients and ringing. Without a bypass capacitor, large current surges or an output short may cause sufficient ringing on V (from supply lead inductance) to cause erratic operation of MIC2004/2014’ ...
