Description
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 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
