BD30HA3MEFJ-ME2

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

The BD30HA3MEFJ-ME2 is a single-output low-dropout (LDO) linear voltage regulator manufactured by ROHM Semiconductor. It provides a fixed 3.3V output with a maximum continuous current of 300mA. The device operates within an input voltage range of 4.5V to 8V and delivers a typical dropout voltage of 600mV at full load. It features high accuracy with ±1.0% output voltage tolerance at 25°C. The regulator includes built-in protection circuits for overcurrent, thermal shutdown, and an ON/OFF switch function that reduces standby current to 0µA. It is housed in a compact HTSOP-J8 surface-mount package.

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

Verify the component status before procurement as this part is marked as NRND (Not Recommended for New Designs). Confirm availability through authorized distributors or existing stock channels. Ensure the HTSOP-J8 package compatibility matches your PCB footprint requirements. Check for RoHS compliance documentation if required for your specific manufacturing standards.

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

Select this regulator when a fixed 3.3V supply is needed with moderate current demands up to 300mA. It is suitable for applications where input voltages are between 4.5V and 8V. Consider the thermal performance in the HTSOP-J8 package under maximum load conditions. Verify that the ±1.0% accuracy meets your circuit's tolerance requirements compared to adjustable alternatives.

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

This component belongs to the BDxxHA3WEFJ series of LDO regulators from ROHM Semiconductor. These devices are designed for automotive and general electronic applications, offering high accuracy and robust protection features. The series utilizes the HTSOP-J8 package to provide efficient heat dissipation in a small form factor, supporting both fixed and variable output configurations depending on the specific suffix.

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

Check for direct substitutes within the same family, such as other fixed voltage variants like BD15HA3MEFJ-ME2 or BD33HA3MEFJ-ME2, ensuring pin compatibility and electrical specifications match your design needs. Since this part is NRND, evaluate newer generation replacements from ROHM or equivalent parts from other manufacturers that meet the 300mA and 3.3V fixed output criteria.
