L9001 SPS (Simple Power Supply) device is a multiple power regulator for Automotive applications with one buck regulator, one configurable buck or linear regulator and one linear regulator. Its output voltages are configurable via discrete pins.

On top of the regulators, this device integrates a watchdog functional block, and a diagnosis functional block (under/over voltage, output current and temperature).

Device is capable of low power operation mode with main regulators still active and reduced power consumption from battery.
