Dual Voltage Regulator with 5 V and 15 V Outputs TLE 4484 Features • • • • • • • • Dual output: 5 V and 15 V High input voltage range: up to 45 V High output current capability High output voltage accuracy Very low current consumption Short circuit protected Over-temperature protected Thermal and space optimized package SOT-223 Type Ordering Code Package TLE 4484 G Q67006-A9396 P-SOT223-4-2 (SMD) Functional Description The TLE 4484 G is a monolithic integrated voltage regulator providing two output voltages, output Q5 is a 5 V output for loads up to 25 mA and output Q15 is a 15 V output providing up to 30 mA. The device is based on the Infineon double isolated bipolar technology DOPL with high accuracy polysilicon resistors and is available in the SOT223 (SMD) package. The TLE 4484 G is designed to supply systems with a microcontroller (5 V) and a standard MOS-driver-IC (15 V) under severe conditions and is therefore equipped with additional protection functions. Both outputs are protected against overload, short circuit to ground and to the input voltage. A build-in shutdown-circuit protects the device against overheat. The IC operates in a wide input voltage range up to 45 V. The output voltages are regulated to VQ5 = 5 V and VQ15 = 15 V with a drop voltage less than 1.5 V. The standard SOT223 (SMD) package is especially suitable for this kind of application, saves PCB-board-space and reduces system cost.

The voltage regulator should not be operated continuously at 170 °C as device reliability will be reduced to 500 h. Note: Stresses above those listed here may cause permanent damage to the device. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
