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

Verify the specific suffix CE2 against official ROHM documentation to confirm pinout and packaging details. Ensure compatibility with AEC-Q100 automotive standards if used in safety-critical environments. Cross-reference datasheet revision dates to validate parameter accuracy before finalizing procurement specifications.

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

Select this component when an adjustable output voltage is required within the 1 V to 18 V range. It is suitable for applications needing 500 mA continuous current with low quiescent current consumption. Consider the TO-252-5 package for surface-mount assembly constraints and verify thermal dissipation requirements based on input-output voltage differentials.

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

This part belongs to the BD9xxN5 series of LDO regulators designed for automotive use. It shares the QuiCur topology with other models in the family but differs in output adjustability compared to fixed-voltage variants like the BD933N5WFP-CE2. The series emphasizes low current consumption and robust performance under varying automotive electrical conditions.

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

The BD900N5WEFJ-CE2 offers identical electrical specifications but uses an HTSOP-J8 package instead of TO-252-5. Verify footprint compatibility before substitution.
