Description
The TLE7276-2 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
Q,nom
= 5.0 V with a precision of ±2%. 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 TLE7276-2 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 TLE7276-2 is dedicated for use in applications
permanently connected to
V
BAT
. In addition the device can be switched off via the Enable input reducing the current
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 TLE7276-2. A mV-range output noise on the TLE7276-2 caused by the charge
pump operation is unavoidable due to the ultra low quiescent current concept.
