BD50GA5MEFJ-LBH2

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

The BD50GA5MEFJ-LBH2 is a fixed-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor. It provides a stable 5V output with a maximum current capacity of 500mA. The device operates within an input voltage range of 4.5V to 14V and features a typical dropout voltage of 600mV at full load. Packaged in an HTSOP-J8 surface-mount format, it supports industrial temperature ranges from -40°C to +105°C. Key electrical characteristics include a circuit current of 600µA and high line/load regulation performance.

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

Verify the specific suffix LBH2 against the official datasheet to confirm package dimensions and marking details. Confirm RoHS compliance status for your region. Check if the component is marked as NRND (Not Recommended for New Designs) to assess long-term availability risks before finalizing procurement plans.

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

Select this LDO when a fixed 5V rail is required with moderate current demands up to 500mA. Ensure the input voltage remains between 4.5V and 14V. Verify that the thermal dissipation capabilities of the HTSOP-J8 package are sufficient for the expected ambient temperature and load conditions.

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

This component belongs to the BDxxGA5MEFJ series of automotive-grade LDO regulators. While designed for robust performance, the specific LBH2 variant is intended for industrial and general applications rather than strict automotive functional safety requirements. It shares the same physical footprint as other variants in the family for design flexibility.

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

Consult the manufacturer's cross-reference list for direct pin-compatible substitutes. Consider the BD50GA5WEFJ series for standard commercial grade alternatives if automotive/industrial qualification is not strictly required. Verify that any replacement maintains the 500mA output current and 5V fixed output specification.
