Description

The TLE7272-2 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

circuitry featuring power on timing and output voltage monitoring the IC is

well suited as

µ-controller supply. The sophisticated design allows 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 TLE7272-2 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 TLE7272-2 is dedicated for use in applications

permanently connected to

V

consumption to typically 5

µA. An 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 TLE7272-2. A mV-range output noise on the TLE7272-2 caused by the charge

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