The L4979D-E is an automotive low dropout linear voltage regulator designed for applications requiring high precision and low quiescent current. It operates within a DC supply voltage range of 5.6 V to 31 V and can handle a maximum input voltage of 40 V. The device features a low dropout voltage of less than 0.5 V and provides an output current that is internally limited, ensuring protection against short circuits and thermal shutdown. This regulator is AEC-Q100 qualified, making it suitable for automotive applications. It offers a typical quiescent current of 6 ¬µA when disabled, and maintains high output voltage accuracy of ¬±2% across a wide temperature range from -40 ¬8C to 150 ¬8C. Additional features include a reset circuit that senses output voltage down to 1 V, a programmable reset pulse delay, and a watchdog timer that can be configured with an external capacitor. The L4979D-E is available in SO-8 and SO-20 packages, making it versatile for various PCB layouts.
