STMicroelectronics L9001 Simple Power Supply (SPS)

STMicroelectronics L9001 Simple Power Supply (SPS) is a multiple power regulator for Automotive applications with one buck regulator, one configurable buck or linear regulator, and one linear regulator. The device's 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). The L9001 can operate in low power mode with active main regulators and reduced battery power consumption.
