Overview

The BD450M2WFP3-CE2 is an automotive-grade linear voltage regulator from Rohm Semiconductor that provides a stable 5V output at up to 200mA. It features an extremely low quiescent current of 40uA and a wide input voltage range up to 42V, making it ideal for battery-connected automotive systems. The device is AEC-Q100 qualified and includes an enable control pin for power management.

Why Choose This Part

This regulator offers high reliability in harsh environments with an operating temperature range of -40C to +150C. It integrates over-current and thermal shutdown protection in a compact SOT-223-4F package, ensuring robust performance against electrical faults.

Applications

Automotive Body Electronics
Providing regulated 5V power to BCUs and lighting controllers directly from the 12V vehicle battery.
Infotainment and Navigation
Supplying clean power to audio processors and GPS modules while maintaining low standby current.
Always-On Sensor Nodes
Ideal for modules that must remain active when the engine is off, thanks to the 40uA typical quiescent current.
Industrial Control Systems
Utilizing the 42V maximum input rating for 24V nominal industrial power rails needing a 5V logic supply.
