BCR112E6327: High-Efficiency Linear Regulator for Automotive and Industrial Applications

In the demanding worlds of automotive electronics and industrial control systems, power management is paramount. Voltage regulators must deliver exceptional reliability, high efficiency, and robust performance under the most challenging conditions. The BCR112E6327 is a monolithic integrated linear voltage regulator engineered specifically to meet these rigorous requirements, offering a compelling solution for a wide array of applications.

This regulator is designed to provide a fixed output voltage of 3.3V from an input voltage range spanning from 4V to 42V. Its ability to handle such a wide input range makes it exceptionally versatile, capable of enduring the severe load-dump and transient voltage spikes common in 12V and 24V automotive battery systems, as well as the unstable power rails found in industrial environments. A key feature of the BCR112E6327 is its remarkably low dropout voltage, which minimizes power dissipation and enhances overall system efficiency—a critical factor for always-on applications and those with limited thermal headroom.

Beyond its core regulation function, the BCR112E6327 is packed with protective features that ensure long-term system integrity. It incorporates internal current limiting and thermal shutdown mechanisms, safeguarding both the IC and the load from damage due to overloads or excessive ambient temperatures. Furthermore, its high power supply rejection ratio (PSRR) ensures a clean, stable output voltage, free from noise and ripple originating from the input, which is vital for powering sensitive microcontrollers and sensors.

The device's high level of integration, requiring only two external capacitors for operation, simplifies board design, reduces the bill of materials (BOM), and saves valuable PCB space. Its SOT143B package is optimized for automated assembly processes, ensuring manufacturing efficiency and reliability.

Typical applications are extensive, including:

Powering Body Control Modules (BCMs), infotainment systems, and instrumentation clusters in vehicles.

Serving as a reliable supply for sensors, actuators, and control units in factory automation and process control.

Providing a stable voltage rail in telematics and always-connected modules.

ICGOOODFIND: The BCR112E6327 stands out as a robust, highly integrated linear regulator that masterfully balances performance with protection. Its wide input voltage range, high efficiency, and built-in safeguards make it an ideal choice for designers seeking a dependable power management solution for harsh automotive and industrial environments.
