Functional Description
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 15 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. To reduce external components the Power Fail Output is internally pulled-up
to the output Q by a 50 KO resistor.
The device incorporates a temperature protection that disables the circuit at over
temperature.
