BD30HA5MEFJ-ME2

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

The BD30HA5MEFJ-ME2 is a single-output low-dropout linear regulator manufactured by ROHM Semiconductor. It provides a fixed 3.0 V output with a maximum continuous current of 0.5 A. The device operates within an input voltage range of 4.5 V to 8 V and features a typical dropout voltage of 600 mV at full load. It is housed in an HTSOP-J8 surface-mount package and supports an operating temperature range from -40°C to +105°C. The regulator includes built-in protection circuits for overcurrent and thermal shutdown.

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

• Integrated overcurrent protection circuit prevents IC damage during output short circuits or overload conditions.
• Thermal shutdown circuit protects the device from thermal destruction caused by excessive heat generation.
• Shutdown function reduces circuit current to zero microamperes when disabled, minimizing power consumption.

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

• Digital home appliances requiring stable low-voltage power supply
• Industrial systems needing reliable linear regulation
• General-purpose electronic equipment utilizing standard voltage rails

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

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific part number matches the required fixed 3.0 V output specification. Check datasheet revisions for any updates regarding electrical characteristics or packaging details. Ensure compliance with RoHS directives if applicable to your manufacturing region. Validate that the HTSOP-J8 footprint aligns with your PCB design constraints before finalizing procurement orders.

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

Select this regulator when a fixed 3.0 V rail is required with up to 500 mA load capability. Consider its 600 mV dropout voltage against your minimum input voltage to ensure proper regulation under all load conditions. Evaluate the thermal performance within your enclosure design due to the 2.11 W power dissipation rating. Compare against adjustable variants if flexible voltage settings are needed instead of fixed outputs.

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

This component belongs to the BDxxHA5WEFJ series of low-dropout regulators designed for general-purpose applications. Unlike automotive-grade counterparts, this specific model is not recommended for use in vehicle electronics. It shares the HTSOP-J8 package form factor with other members of the family but differs in output voltage precision and intended application environment classification.
