BD450M2EFJ-CE2

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

The BD450M2EFJ-CE2 is a fixed-output low dropout regulator manufactured by ROHM Semiconductor, housed in an HTSOP-J8 surface-mount package. It provides a stable 5 V output with a maximum continuous current of 200 mA. The device operates within an input voltage range of 5.5 V to 42 V and maintains a typical quiescent current of 40 uA. Key electrical specifications include a typical dropout voltage of 160 mV at 100 mA load, a ripple rejection ratio of 65 dB, and line/load regulation of 10 mV. It is qualified under AEC-Q100 standards for automotive reliability.

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

Verify the component status before procurement as this specific part number is classified as NRND (Not Recommended for New Designs). Confirm that existing inventory or last-time buy options align with long-term production requirements. Ensure compatibility with the HTSOP-J8 footprint and validate that the 5 V fixed output meets system design specifications without modification.

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

Select this component for designs prioritizing automotive qualification and high input voltage tolerance. The 200 mA output current is sufficient for moderate load applications. Consider the NRND status when planning future product lifecycles. Verify that the 40 uA quiescent current meets power efficiency targets for standby modes in battery-operated equipment.

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

This regulator belongs to the BD450M2EFJ-C series, which offers similar technical characteristics but may involve manufacturing line changes. The BD450S2EFJ-C series serves as a recommended alternative for new designs, providing equivalent performance metrics while maintaining active production status. Both series share the same core functionality and protective features.

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

The BD450S2EFJ-CE2 is a recommended replacement for new designs, offering identical electrical specifications and pinout compatibility. Verify that the S-series designation does not introduce subtle differences in packaging or testing criteria compared to the M-series variant currently in use.
