The TLE 4285 G is a 5-V low-drop fixed voltage regulator in a very small SMD package SCT-595. The maximum input voltage is 45 V. The output is able to drive a load of more than 10 mA while it regulates the output voltage within a 4% accuracy.
The Power Fail Output (open collector) is switched to low in case of under-voltage at the output pin.
The device incorporates a temperature protection that disables the circuit at over temperature.
