Description

The TLE7274-2 is a monolithic integrated low dropout voltage regulator

for load currents up to 300 mA. An input voltage up to 42 V is regulated

to

V

to achieve stable operation even with ceramic output capacitors down to

470 nF. The device is designed for the harsh environment of automotive

applications. Therefore it is protected against overload, short circuit and

overtemperature conditions by the implemented output current limitation

and the overtemperature shutdown circuit. The TLE7274-2 can be also

used in all other applications requiring a stabilized 5 V voltage.

Due to its ultra low quiescent current of typically 20 µA the TLE7274-2 is

dedicated for use in applications permanently connected to

V

integrated output sink current circuitry keeps the voltage at the Output pin

Q below 5.5 V even in case of occuring reverse currents. Thus connected

devices are protected from overvoltage damage. For applications

requiring extremely low noise levels the Infineon voltage regulator family

TLE 42XX and TLE 44XX is more suited than the TLE7274-2. A mV-

range output noise on the TLE7274-2 caused by the charge pump

operation is unavoidable due to the ultra low quiescent current concept.
