Functional Description

The TLE 4285 G is a 5-V fixed voltage regulator in a very small SMD package

PG-SCT-595-5. The maximum input voltage is 45 V. The output is able to drive an output

current 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. To reduce external components the Power Fail Output has an internal pull-up

resistor of 50 kΩ which is connected to the output Q.

The device incorporates a temperature protection that disables the circuit at

overtemperature.
