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_Q5 = 5 V and V_Q15 = 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.
