| 5-V Voltage Regulator TLE 4286 G Features Wide operation range: 6.2 V to 42 V Wide temperature range: - 40 C to 150 C Low quiescent current consumption: 50 A Output protected against short circuit Over-temperature protection Inhibit input Very low current consumption in stand-by (Inhibit) mode * Very small SMD-Package SCT-595 * * * * * * * SCT-595 Type TLE 4286 G Ordering Code Q67006-A9304 Package SCT-595 (SMD) Functional Description The TLE 4286 G is a 5-V low-drop fixed voltage regulator in the very small SMD package SCT-595. The maximum input voltage is 42 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 device can be switched in stand-by mode via an inhibit input which causes the current consumption to drop below 1 A. A temperature protection that disables the circuit at over temperature is incorporated.
