Additional Details

The TLE4240-2M is designed with various protection features to ensure reliable operation in automotive environments. The overtemperature protection disables the output voltage if the chip temperature exceeds a certain threshold, preventing damage to the regulator. The short-circuit protection limits the output current in the event of a short circuit, protecting both the regulator and the connected load. The reverse polarity protection prevents damage from accidental reverse connection of the battery. The very low quiescent current minimizes power consumption when the regulator is in standby mode, extending battery life. The wide input voltage range allows the regulator to operate with a variety of automotive battery voltages. The TLE4240-2M is typically packaged in a PG-DSO-8 package.
