TLE7274-2 5-V Low Dropout Voltage Regulator TLE7274-2E TLE7274-2D TLE7274-2G Data Sheet Rev. 1.01, 2011-11-30 Automotive Power 5-V Low Dropout Voltage Regulator TLE7274-2 1Overview Features Ultra Low Current Consumption 20 A Output Voltage 5 V 2% Output Current up to 300 mA Very Low Dropout Voltage Output Current Limitation Overtemperature Shutdown Wide Temperature Range From -40 C up to 150 C Green Product (RoHS compliant) PG-SSOP-14 Exposed Pad AEC Qualified Description The TLE7274-2 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 = 5.0 V with a precision of 2%. The sophisticated design allows Q,nom 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 TLE7274-2 can be also PG-TO252-3 used in all other applications requiring a stabilized 5 V voltage. Due to its ultra low quiescent current of typically 20 A the TLE7274-2 is dedicated for use in applications permanently connected to V . An BAT 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 TLE7274-2. A mV- range output noise on the TLE7274-2 caused by the charge pump operation is unavoidable due to the ultra low quiescent current concept.
