Functional Description
The TLE 4418 G is a monolithic integrated voltage regulator with a fixed triple output
voltage of 2.6 V with max. 1.2 A, 3.3 V with max. 1.2 A and 8.0V with max. current 0.2 A.
The regulator is supplied by two input voltages: VCC (nominal 5 V)= 4.75 V to 40 V and
VDD (nominal 12 V)= 10.8 V to 40 V. It can also be operated without the VDD input voltage
resulting in a reduced output voltage precision/ higher drop voltage. The IC is short
circuit proof due to its integrated overcurrent and overtemperature protection circuits.
The operating temperature range extends from TJ=0°C to 125°C with a thermal
shutdown disabling all output voltages at typ. 150°C.

Circuit Description
Each of the output voltages features a reference voltage kept highly accurate by internal
resistance adjustment. An error amplifier compares this reference voltage to the divided
output voltage and drives the base of the Darlington power element. Over-saturation of
the power element is prevented by an integrated saturation control circuit. While the
output current is driven by VCC maintaining a reasonable power dissipation the higher
voltage level at VDD allows to keep the drop voltage relatively low and supplies the 8.0 V
output. The regulation loops are kept stable even for low output capacitances down to
2.2 µF (ESR £ 4 W).

Application Information
The output capacitors CQ2, CQ3 and CQ8 are required with a capacitance of CQ2/3/8³2.2 µF
and an ESR £ 4 W in order to maintain the stability of the regulation loop under all
operating conditions. The output capacitors should be placed nearby the corresponding
output voltage pin. For the Inputs VCC and VDD a ceramic capacitor in the range of
100 nF... 470 nF connected to GND close to the pins is needed in order compensate line
influences.
