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 P-SOT223-4-2 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 V. The standard

P-SOT223-4-2 package is especially suitable for this kind of application, saves PCBboard-space and reduces system cost.
