BD30IA5JEFJ-E2

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

The BD30IA5JEFJ-E2 is a low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor, designed for stable power delivery in compact electronic systems. It provides a fixed output voltage of 3.0 V with a maximum output current capability of 0.5 A. The device operates within an input voltage range of 2.4 V to 5.5 V and maintains high accuracy with a ±1.0% output tolerance at 25°C. Key electrical characteristics include a typical dropout voltage of 0.4 V at full load, a ripple rejection of 60 dB, and a quiescent current of 0.25 mA. It features integrated protection mechanisms such as overcurrent protection, thermal shutdown, and a shutdown function that reduces circuit current to 0 µA.

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

Verify the specific suffix JEFJ against the manufacturer's latest datasheet to confirm pinout and electrical specifications, as production lines may vary. Ensure compatibility with HTSOP-J8 packaging requirements. Confirm RoHS compliance status through official documentation before integration. Check for any updates regarding the recommended new development status versus legacy models like BD30IA5WEFJ.

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

Select this component for applications requiring a fixed 3.0 V output with moderate current demands up to 0.5 A. It is suitable for designs prioritizing high voltage accuracy and built-in safety protections. Consider the HTSOP-J8 package for its thermal performance and small footprint. Note that this model is recommended for new developments compared to older series variants.

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

This LDO regulator belongs to ROHM's high-accuracy linear regulator family, optimized for consumer electronics. It utilizes a specialized production line distinct from the WE series to improve manufacturing efficiency while maintaining identical electrical characteristics. The device is classified as a standard-grade product intended for general commercial use rather than automotive environments.

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

The BD30IA5WEFJ series shares identical electrical characteristics and can serve as a functional substitute. Designers should verify that the alternative package type meets the PCB layout constraints. No functional changes are implied by the different production line designation.
