Description
The 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 V_Q,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
