... AEC Qualified Description The TLE42994G is a monolithic integrated low dropout voltage regulator, especially designed for automotive applications that need state during the car’s engine is turned off. An input voltage regulated to an output voltage of 5.0 V. The component is able to drive loads up to 150 mA ...

... The additional sense comparator provides an early warning function: Any voltage (e.g. the input voltage) can be monitored, an under-voltage condition is indicated by setting the comparator’s output to low. The TLE42994GM (PG-DSO-14 package) and TLE42994E (PG-SSOP-14 package) include additionally an Enable function permitting enabling/disabling the regulator. In case the regulator is disabled it consumes less current than 1 µ ...
