Functional DescriptionThe
TLE4484G is a monolithic integrated voltage regulator providing two outputvoltages, output Q5 is a 5V output for loads up to 25mA and output Q15 is a 15V output
providing up to 30mA. 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
TLE4484G is designed to supply systems with a microcontroller (5V) and a
standard MOS-driver-IC (15V) 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 45V. The output voltages are
regulated to VQ5=5V and VQ15=15V with a drop voltage less than 1.5V. The standard
SOT223 (SMD) package is especially suitable for this kind of application, saves
PCB-board-space and reduces system cost.
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.

ESD-Protection (Human Body Model)The overtemperature protection will be set to 150°C min. The voltage regulator should not be operated
continuously at 170°C as device reliability will be reduced to 500h.
Note:In the operating range, the functions given in the circuit description are fulfilled.
