BD30HC5JEFJ-E2

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

The BD30HC5JEFJ-E2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 3 V output with a maximum current capacity of 1.5 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, with a maximum of 930 mV. It utilizes an HTSOP-J8 surface-mount package suitable for compact designs. The regulator maintains line regulation at 1% and load regulation at 1.5%. It includes built-in protection mechanisms such as overcurrent protection and thermal shutdown. The component supports operation in temperatures from -25°C to +85°C and incorporates a shutdown function that reduces circuit current to 0 µA.

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

• Integrates overcurrent protection and thermal shutdown circuits to prevent IC damage during short circuits or overload conditions.
• Features a dedicated ON/OFF switch that reduces circuit current to zero amperes when the shutdown function is activated.
• Designed for compatibility with ceramic capacitors to support miniaturization and extended lifespan of end equipment.

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

• Digital home appliances
• General-purpose power management systems
• Portable electronic devices requiring stable 3 V rails

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

Verify the specific suffix E2 against the manufacturer's latest documentation to confirm compliance with current RoHS directives and material declarations. Confirm the HTSOP-J8 package dimensions match the target PCB footprint. Ensure the input voltage does not exceed the 8 V maximum rating under all operating conditions to maintain device integrity.

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

Select this component for applications requiring a fixed 3 V output with high current capability up to 1.5 A. It is suitable for designs where a low dropout voltage is critical for efficiency. The inclusion of thermal and overcurrent protection makes it robust for consumer electronics. Note that this standard-grade product is not recommended for automotive equipment; consider the BD30HC5VEFJ-ME2 variant if automotive qualification is required.

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

This LDO regulator belongs to the BD30HC5 series, which shares electrical characteristics with the BD30HC5WEFJ model despite using different production lines for efficiency. The BD30HC5JEFJ-E2 is designated as a recommended part for new developments. It offers a long-term supply plan of ten years, ensuring availability for sustained manufacturing cycles.

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

The BD30HC5WEFJ is electrically equivalent but uses a different production line. For automotive applications, the BD30HC5VEFJ-ME2 serves as the qualified alternative with an extended temperature range of -40°C to +105°C.
