Low Drop Voltage Regulator TLE 7273 • Output voltage 5 V, V or V • Output voltage tolerance ±2% up to IQ=180mA • Ultra low quiescent current consumption < 35 µA • Inhibit function • Very low dropout voltage • Reset with adjustable power-on delay • Window watchdog with current dependent deactivation • Output protected against short circuit • Wide operation range up to 45 V • Wide temperature range -40 °C to 150 °C • Overtemperature Shutdown P-DSO-14-3, -8, -9, -11, 14 Functional Description The TLE 7273 is a monolithic integrated 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 TLE 7273 is perfectly suited for applications that are permanently connected to battery. In addition, the regulator can be shut down via the Inhibit input causing the current consumption to drop below 3 µA. The TLE 7273 is equipped with protection functions against overload, short circuit and overtemperature. It operates in the wide junction temperature range from -40 °C to 150 °C.

Functional Description

The TLE 7273 is a monolithic integrated 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 TLE 7273 is perfectly suited for applications that are permanently connected to battery. In addition, the regulator can be shut down via the Inhibit input causing the current consumption to drop below 3 µA. The TLE 7273 is equipped with protection functions against overload, short circuit and overtemperature. It operates in the wide junction temperature range from -40 °C to 150 °C.
