BD30HC5MEFJ-ME2

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

The BD30HC5MEFJ-ME2 is a high-accuracy automotive LDO regulator manufactured by ROHM Semiconductor. It provides a fixed 3 V output with a maximum current 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 900 mV. Line and load regulation are specified at 25 mV each. It includes shutdown functionality, thermal shutdown, and overcurrent protection. The component is housed in an HTSOP-J8 package and supports an operating temperature range from -40 °C to +105 °C.

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

Verify the specific suffix ME2 against official ROHM documentation to confirm pinout and functional compatibility. Ensure the HTSOP-J8 package dimensions match your PCB footprint requirements. Confirm that the 8 V maximum input voltage aligns with your system's supply rails to prevent damage. Check for RoHS compliance status in the latest datasheet before finalizing procurement.

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

Select this component when a fixed 3 V output is required with high precision in automotive settings. The 1.5 A current capability suits moderate load applications. Consider the 4.5 V minimum input voltage constraint during system design. The wide operating temperature range ensures reliability in harsh automotive environments compared to commercial-grade alternatives.

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

This part belongs to the BDxxHC5 series of high-accuracy LDO regulators designed specifically for automotive use. It shares the HTSOP-J8 package form factor with other variants in the family, such as BD15HC5MEFJ-ME2 and BD60HC5VEFJ-ME2, which offer different fixed or adjustable output voltages while maintaining similar current and protection characteristics.

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

BD30HC5MEFJ-M is a previous generation version of this component. Verify if the ME2 suffix indicates any functional or packaging changes before substitution. Other fixed 3 V outputs in the HC5 series may serve as alternatives if input voltage ranges and current ratings are compatible.
