Features
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
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
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
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.
