Description
PG-SSOP-14 Exposed Pad
The TLE7278-2 is a monolithic integrated voltage regulator with integrated standard watchdog and reset dedicated
for microcontroller supplies under harsh automotive environment conditions. 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.
