BD15IC0MEFJ-ME2

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

The BD15IC0MEFJ-ME2 is a single-output low-dropout linear regulator manufactured by ROHM Semiconductor, designed for automotive applications. It provides a fixed 1.5 V output with a maximum continuous current of 1 A. The device operates within an input voltage range of 2.4 V to 5.5 V and features a typical dropout voltage of 0.4 V 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 component holds AEC-Q100 qualification and includes built-in protection circuits.

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

This component carries the status NRND (Not Recommended for New Designs), indicating it is not intended for new development projects. Procurement should be limited to supporting existing designs or replacement needs. Verify AEC-Q100 qualification and RoHS compliance through official datasheets before integration. Confirm package integrity and pin configuration matches HTSOP-J8 specifications.

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

Select this regulator only for legacy automotive designs requiring a 1.5 V fixed output at 1 A. Consider the NRND status carefully; alternative newer models may offer better availability. Ensure input voltage remains within 2.4 V to 5.5 V limits. Verify thermal performance given the 2.11 W power dissipation capability in the HTSOP-J8 package. Check if ceramic capacitor compatibility meets system stability requirements.

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

The BD15IC0MEFJ-ME2 belongs to ROHM's automotive-grade LDO series, specifically engineered for high reliability in vehicle environments. It is part of the BD15IC0MEFJ family, which shares production lines with other variants like BD15IC0JEFJ. While electrical characteristics remain consistent across these lines, the ME2 suffix denotes specific packaging and automotive qualification standards.

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

BD15IC0JEFJ is referenced as an alternative produced on different lines with identical electrical characteristics. No other direct substitute part numbers are confirmed in public documentation. Verify compatibility with existing PCB layout and thermal design before switching.
