| Triple Voltage Regulator Target Data Features * Triple Output voltage 2.6 V(1.2 A), 3.3 V(1.2 A) and 8.0 V(0.2 A) * Wide input voltage range * Overtemperature protection * Short circuit proof * SMD-Power package TLE 4418 G P-SFMG-7-1 Type TLE 4418 G New type Ordering Code Package P-SFMG-7-1 (SMD) 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=0C to 125C with a thermal shutdown disabling all output voltages at typ. 150C.

Target Data Sheet Rev. 0.1 2 2001-12-10 TLE 4418 G 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 F (ESR 4 W).

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.
