TLE42994G The TLE42994G is a monolithic integrated low dropout voltage regulator, especially designed for automotive applications that need to be in ON state during the car’s engine is turned off.
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,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 undervoltage condition is indicated by setting the comparator’s output to low.
This product is an alternative to product TLE4269G.
