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

V

SOT223 (SMD) package is especially suitable for this kind of application, saves

PCB-board-space and reduces system cost.
