TLE4678-2LD

综述

描述:

The TLE4678-2LD is a monolithic integrated low dropout 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 TLE4678-2LD 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. The TLE4678-2LD is available in a small thermally enhanced PG-SSOP-14 exposed pad package.
