5-V Voltage Regulator Preliminary Data Features * * * * * * * * Wide operation range: 6 V to 45 V Wide temperature range: - 40 C to 150 C Low quiescent current consumption: 80 A Output protected against short circuit Over-temperature protection Power fail output SMD-Package SCT-595 Power Fail Output TLE 4285 G SCT-595 Type TLE 4285 G Ordering Code Q67006-A9328 Package SCT-595 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 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.
