Infineon TLE42794E

The OPTIREG Linear TLE42794 is a monolithic integrated low dropout voltage regulator, especially designed for automotive applications. An input voltage up to 45 V is regulated to an output voltage of 5.0 V. The component is able to drive loads up to 150 mA. It is short-circuit protected by the implemented current limitation and has an integrated overtemperature shutdown. A reset signal is generated for an output voltage VQ,n of typically 4.65 V. This threshold can be decreased by an external resistor divider. The power-on reset delay time can be programmed by the external delay capacitor. The additional sense comparator provides an early warning function: Any voltage (e.g. the input voltage) can be monitored, an under-voltage condition is indicated by setting the comparator’s output to low. If pull-up resistors are desired at the outputs of the reset and the sense comparator, the TLE42694 with integrated pull-up resistors can be used instead of the TLE42794.
