BD25HC5MEFJ-LBH2

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

The BD25HC5MEFJ-LBH2 is a fixed positive single-output Low Dropout (LDO) linear regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 2.5 V with a maximum output current of 1 A. The device operates within an input voltage range of 4.5 V to 8 V and features a typical dropout voltage of 0.6 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.

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

• Integrated over-current protection circuit to prevent IC damage during output short circuits
• Built-in thermal shutdown circuit to protect against heat destruction under overload conditions
• Includes a shutdown switch that reduces circuit current to 0 µA when disabled

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

• Digital home appliances
• Industrial equipment power management
• General-purpose low-noise voltage regulation

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

Verify the specific suffix LBH2 against the official datasheet to confirm pinout and electrical characteristics, as suffixes may indicate variations in packaging or testing criteria. Confirm availability status, as some variants in this series are marked as Not Recommended for New Designs (NRND). Ensure compatibility with ceramic output capacitors as specified in the technical documentation.

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

Select this component for applications requiring a stable 2.5 V supply with up to 1 A load capability. The HTSOP-J8 package offers thermal efficiency suitable for compact designs. Consider the 4.5 V minimum input requirement and the 600 mV dropout voltage when designing the power rail. Verify that the application environment stays within the -40°C to +105°C operating temperature range.

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

This part belongs to the BDxxHC5MEFJ series of LDO regulators designed for industrial and consumer markets. The series is characterized by high accuracy reference voltage circuits and robust protection features. The HC5 variant specifically denotes the 1.5 A class devices, though individual models like this one are rated for 1 A output depending on the specific voltage setting and thermal constraints.

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

Check for other members of the BD25HC5MEFJ family with different suffixes if the LBH2 package or tape-and-reel configuration is unavailable. Cross-reference with BD25HA5MEFJ variants for similar performance in automotive-grade applications if higher reliability standards are required.
