Low Dropout Fixed Voltage Regulator

The TLE 42694 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 proof by the implemented output current limitation and has an integrated overtemperature shutdown. A reset signal is generated for an output voltage VQ,rt 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. The reset and sense output are internally connected to the output Q via a pull-up resistor. If these By Infineon Technologies Corporation
