Functional Description

The TLE 7272 is a monolithic integrated low-drop

voltage regulator for load currents up to 300 mA. An input

voltage up to 42 V is regulated to V_Q,nom= 5.0 V with a

precision of ±2%. Due to its integrated reset 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

P-TO263-5-1

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 7272 can be used also in all other applications, where a stabilized 5 V voltage is

required. Due to its ultra low stand-by current consumption of typ. 20 µA the TLE 7272

is dedicated for use in applications permanently connected to V_BAT. In addition the IC can

be switched off via the Inhibit input reducing the current consumption to typ. 5 µA. An

integrated output sink current circuitry keeps the 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 7272. A

mV-range output noise on the TLE 7272 caused by the charge pump operation is

unavoidable due to the ultra low quiescent current concept.
