Data Sheet, Rev. 1.2, April 2009 TLE7273-2 Low Dropout Voltage Regulator Automotive Power Low Dropout Voltage Regulator TLE7273-2 1Overview Features Output Voltage 5 V, 3.3 V or 2.6 V Output Voltage Tolerance 2% Up To 180mA Ultra Low Quiescent Current Consumption < 36 A Enable Function Very Low Dropout Voltage Reset With Adjustable Power-On delay Window Watchdog With Current Dependent Deactivation PG-DSO-14 Output Current Limitation Wide Operation Range Up To 45 V Wide Temperature Range From -40 C To 150 C Overtemperature Shutdown Green Product (RoHS compliant) AEC Qualified Description PG-SSOP-14 Exposed Pad The TLE7273-2 is a monolithic voltage regulator with integrated window watchdog and reset dedicated for microcontroller supplies under harsh automotive environment conditions. Due to its ultra low quiescent current, the TLE7273-2 is perfectly suited for applications that are permanently connected to battery. In addition, the regulator can be shut down via the Enable input causing the current consumption to drop below 3 A. The TLE7273-2 is equipped with an output current limitation and an overtemperature shutdown, protecting the device against overload, short circuit and over-temperature. It operates in the wide junction temperature range from -40 C to 150 C.
