Description
The TLE4678 is a monolithic integrated low drop out fixed output voltage regulator for loads up to 200 mA. An
input voltage of up to 45 V is regulated to an output voltage of 5 V. The integrated reset and watchdog function,
as well as several protection circuits, combined with a wide operating temperature range offered by the TLE4678
make it suitable for supplying microprocessor systems in automotive environments.
The watchdog circuitry will be disabled in case the output current drops below a programmable threshold, enabling
a microcontroller to switch in stand-by mode. Modifying the reset threshold is possible by an optional resistor
divider.
