Description

The TLE7276 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 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. Of course the TLE 7276 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 A the TLE 7276is dedicated for use in applications permanently connected to VBAT. The regulator can be shut down via an Inhibit input. 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 TLE7276 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 7276. A mV-range output noise on the TLE7276 caused by the charge pump operation is unavoidable due to the ultra low quiescent current concept.
