L5956 is a multifunction voltage regulator for car radio. It features four outputs: 8.5V @ 500mA, 5V @ 300mA permanent, 5V @ 800mA, and 3.3V @ 800mA. The IC also includes a 2A high side driver, reset function, ignition comparator, load dump protection, thermal shutdown, and overcurrent limitation.
The L5956 is an integrated circuit designed as a multifunction voltage regulator specifically for car radio systems. It incorporates a triple voltage regulator providing three distinct output voltages (8.5V, 5V, and 3.3V) along with a high-side power switch capable of driving up to 2A. The device includes various protection features such as load dump protection, thermal shutdown, overcurrent limitation, and an ignition comparator.
