BD42530EFJ-CE2

Power Management - Specialized Overview

The BD42530EFJ-CE2 is an automotive-grade Low Dropout (LDO) regulator manufactured by ROHM Semiconductor. It operates within a wide input voltage range of 3V to 42V and delivers a maximum output current of 16A. The device features a Voltage Tracker Circuit with an output tracking accuracy of ±10mV. Key electrical specifications include a typical quiescent current of 40µA, a dropout voltage of 0.28V at 200mA, and a ripple rejection of 80dB. It is housed in an HTSOP-J8 package and supports junction temperatures from -40°C to +150°C.

Power Management - Specialized Feature Summary

• Voltage tracker circuit with high precision output tracking
• Wide operating input voltage range suitable for automotive loads
• Integrated over-current protection and thermal shutdown functions

Power Management - Specialized Applications

• Automotive power distribution systems
• High-current load regulation in vehicle electronics
• Battery-powered automotive subsystems requiring stable voltage under varying input conditions

Power Management - Specialized Procurement Notes

Verify the component status before procurement as it is marked NRND (Not Recommended for New Designs). Confirm that existing inventory or last-time buy options meet project timelines. Ensure compatibility with the HTSOP-J8 footprint during final assembly planning. Check for any specific functional safety documentation requirements if used in safety-critical automotive applications.

Power Management - Specialized Selection Notes

Select this component when a high-current LDO with voltage tracking capability is required for automotive environments. Consider the 16A output capacity and wide input range against alternative regulators if lower current or non-tracking functionality suffices. Evaluate the HTSOP-J8 package constraints for thermal management and PCB layout. Verify AEC-Q100 Grade 1 qualification meets system reliability standards.

Power Management - Specialized Part Context

This part belongs to ROHM's automotive PMIC portfolio, designed for robust performance in harsh vehicle environments. It complements other voltage regulators by offering specialized voltage tracking features alongside high current handling. The HTSOP-J8 package provides a compact solution for space-constrained automotive boards while maintaining thermal efficiency.

Power Management - Specialized Replacement Considerations

Check for direct pin-compatible substitutes within the BD425xx series. Verify if newer ROHM LDOs offer improved thermal performance or updated packaging. Ensure any replacement maintains the 16A current rating and voltage tracking accuracy if those features are critical to the design.
