Functional Description

The TLE 7270 is a monolithic integrated low-drop

voltage regulator which can supply loads up to 300 mA.

An input voltage up to 42 V is regulated to

V

with a precision of

±2%. Due to its integrated reset

circuitry featuring a 2-step adjustable power on timing

and output voltage monitoring the IC is well suited for

µ-controller supplies. 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. Of course the TLE 7270 can be

used also in all other applications, where a stabilized 5 V voltage is required. Due to its

ultra low current consumption the TLE 7270 is dedicated for use in applications

permanently connected to

V

voltage at the Output pin Q below 5.5 V even when reverse currents are applied. Thus

connected devices are protected from overvoltage damage. For applications requiring

extremely low noise levels the Infineon voltage regulator family TLE 42XY and

TLE 44XY is more suited than the TLE 7270. A mV-range output noise on the TLE 7270

caused by the charge pump operation is unavoidable due to the ultra low quiescent

current concept.
