BD25GA5MEFJ-LBH2

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

The BD25GA5MEFJ-LBH2 is a single-output fixed low-dropout (LDO) linear voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 2.5 V with a maximum output current of 500 mA. The device operates within an input voltage range of 4.5 V to 14 V and features a typical dropout voltage of 600 mV at full load. Designed for automotive applications, it holds AEC-Q100 qualification and supports an operating temperature range from -40°C to +105°C. The regulator is housed in an HTSOP-J8 surface-mount package.

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 match your design requirements. Confirm AEC-Q100 compliance if automotive qualification is mandatory. Check the latest manufacturer status as this component may be subject to production lifecycle changes.

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

Select this component when a 2.5 V fixed output is required with 500 mA capability in an automotive environment. Ensure the input voltage remains above 4.5 V and consider the 600 mV dropout voltage for headroom calculations. Verify that the HTSOP-J8 package fits the PCB layout constraints and thermal dissipation needs.

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

This part belongs to the BD25GA5 series of high-accuracy LDO regulators designed specifically for automotive use. It shares the HTSOP-J8 package and core topology with other variants in the family but differs in output voltage and specific suffix codes. The series emphasizes low quiescent current and robust protection features suitable for harsh automotive environments.

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

Consult the official datasheet or manufacturer support for confirmed substitute part numbers. Do not assume cross-compatibility with other ROHM LDOs without verifying pinouts, electrical parameters, and automotive qualification status.
