... Thermal Shutdown Thermal shutdown is employed MIC2003/2013 from damage should the die temperature exceed safe operating levels. Thermal shutdown shuts off the output MOSFET and asserts the FAULT/ output if the die temperature reaches 145°C. MIC2003/2013 will automatically resume operation when the die temperature cools down to 135°C. If ...

... I OUT 0 Supply Filtering A 0.1µF to 1µF bypass capacitor positioned close to the V and GND pins of MIC2003/2013 is both good design IN practice MIC2003/2013. 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 MIC2003/2013’ ...
