Product validation Qualified for automotive applications. Product validation according to AEC-Q100. Description The OPTIREG Linear TLE4678 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 TLE4678GM make it suitable for supplying microprocessor systems in automotive environments. Datasheet Rev. 1.21 www.infineon.com/OPTIREG-Linear 1 2019-09-30 OPTIREG Linear TLE4678 Low drop out linear voltage regulator The watchdog circuitry will be disabled in case the output current drops below a programmable threshold, enabling a microcontroller to switch to stand-by mode. Modifying the reset threshold is possible by an optional resistor divider. The TLE4678GM is available in a PG-DSO-14 package which makes it pin-compatible to the TLE4278, as well as in a small thermally enhanced PG-SSOP-14 exposed pad package.
