BD80GA5MEFJ-ME2

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The BD80GA5MEFJ-ME2 is a single-output low-dropout linear regulator manufactured by ROHM Semiconductor. It provides a fixed positive output voltage of 8 V with a maximum continuous output current of 500 mA. The device operates within an input voltage range from 4.5 V to 14 V and supports surface-mount installation in an HTSOP-J8 package. It features a typical dropout voltage of 600 mV at full load, with a maximum of 900 mV. Quiescent current is specified at 900 uA. Line regulation and load regulation are both rated at 25 mV. The unit is qualified under AEC-Q100 standards for automotive reliability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated protection mechanisms including thermal shutdown and overcurrent protection to prevent damage during fault conditions.
• Soft start functionality minimizes inrush current and output voltage overshoot during power-up sequences.
• High-accuracy fixed output voltage maintained with low line and load regulation specifications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Automotive electronic systems requiring AEC-Q100 qualified power management
• Digital home appliances needing stable fixed voltage rails
• Industrial control modules utilizing single-output LDO regulators

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix ME2 against the manufacturer's latest datasheet to confirm pinout compatibility and tape-and-reel specifications. Confirm that the 8 V fixed output aligns with the target circuit requirements, as this variant does not support adjustable outputs. Ensure the HTSOP-J8 package footprint matches the PCB design guidelines provided in the official documentation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a reliable 8 V supply is required for automotive or industrial loads up to 500 mA. The AEC-Q100 qualification makes it suitable for harsh environments where standard commercial parts may fail. Consider the 600 mV typical dropout voltage to ensure sufficient input-to-output headroom under all operating conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the BDxxGA5MEFJ series of high-accuracy LDO regulators designed for automotive applications. It shares the HTSOP-J8 package and protection features with other variants in the family, differing primarily in the fixed output voltage setting. The series is engineered to support functional safety analysis and robust operation across wide temperature ranges.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include BD60GA5MEFJ-ME2 (6 V output) and BD18GA5MEFJ-ME2 (1.8 V output) if voltage levels differ. For higher current needs, consider the BD80GC0VEFJ-ME2 which offers 1 A output in a similar package. Verify thermal performance and pin compatibility before swapping.
