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 VQ,nom = V
with a precision of Due to its integrated reset
circuitry featuring a 2-step adjustable power on timing
and output voltage monitoring the IC is well suited as µ-controller suppliy. The sophisticated design allows to

P-TO263-5-1
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 VBAT. An integrated output sink current circuitry keeps the
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 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.

Reset The Reset pin informs e.g. the microcontroller in case the output voltage has fallen below
the lower threshold VRT of typ. V. The hysteresis is typically 100mV. Connecting the
regulator to a battery voltage at first the reset signal remains LOW. When the output
voltage has reached the reset threshold VRT the reset output RO remains still LOW for the reset delay time trd adjustable in 2 steps via the DT Pin. Afterwards the reset output
turns HIGH.
