BD15HC5MEFJ-ME2

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

The BD15HC5MEFJ-ME2 is a single-output fixed low-dropout linear regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 1.5 V with a maximum output 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 specified at 900 mV. It includes internal protection mechanisms such as over-current protection, thermal shutdown, and soft start functionality. The regulator is housed in an HTSOP-J8 surface-mount package and is qualified under the AEC-Q100 standard for automotive applications.

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

• Integrated over-current protection and thermal shutdown circuits prevent damage during short-circuit or overload conditions.
• Soft start function limits inrush current during power-up to stabilize system initialization.
• AEC-Q100 qualification ensures reliability and compliance for demanding automotive electronic environments.

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

• Automotive infotainment systems requiring stable 1.5 V logic supply
• Engine control unit (ECU) peripheral circuitry
• Body control modules in automotive electronics

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

Verify component authenticity through authorized distribution channels due to the NRND status. Confirm that the specific lot date codes meet project requirements before procurement. Ensure compatibility with existing PCB footprints for the HTSOP-J8 package. Review the official datasheet for any updates regarding end-of-life management or recommended design-in alternatives.

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

Select this component when a fixed 1.5 V output is required with high current capability up to 1.5 A. The narrow input voltage window of 4.5 V to 8 V suits systems with regulated intermediate bus voltages. Consider the AEC-Q100 rating if automotive functional safety standards are mandatory. Evaluate thermal dissipation capabilities given the 2.11 W power dissipation limit in the HTSOP-J8 package.

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

This part belongs to the BD15HC5MEFJ series of automotive-grade LDO regulators from ROHM. It shares the same pinout and form factor as other variants in the family but offers a fixed 1.5 V output. The series is designed to replace older generations while maintaining backward compatibility with existing designs. It supports ceramic capacitors for improved stability and reduced board space.
