Infineon TLE7276-2D

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 VQ,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 VBAT. 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.
