The watchdog circuit is deactivated for very low loads at the device’s output (e.g. microcontroller in standby mode). Due to its ultra low quiescent current the TLE7278-2 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 µA. The TLE7278-2 is equipped with an overtemperature shutdown and an output current limitation protecting the device against overload, short circuit and overtemperature. It operates in the wide junction temperature range from -40 °C to 150 °C.
