The L5957 is a multifunction voltage regulator designed for car radios.
It features four outputs, a high side driver, reset function, ignition comparator, load dump protection, thermal shutdown, and overcurrent limitation.
The IC includes a monitoring circuit for detection and has a very low quiescent current in standby.
It is available in two different packages and has various electrical specifications including absolute maximum ratings, thermal data, and electrical characteristics for each regulator and power switch.
The device is designed to operate within a specific range of operating and storage temperatures and has specific voltage and current requirements for each output.
