2.5 Dropout Operation

In automotive applications, depending on the severity of the cold crank, the supply voltage can drop down to 3V and the part can enter dropout in these conditions. It is preferred to ensure that the part does not operate in dropout during DC operation so that the AC performance is maintained.

The device has a dropout voltage of approximately 380 mV at full load and room temperature, but because of the extended temperature range at 150°C, due to increased leakage, it reaches up to 705 mV.
