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

Verify the complete part number including the suffix to ensure correct package and tape specifications. Confirm RoHS compliance status through official manufacturer documentation before integration. Cross-reference the datasheet for specific handling requirements and ESD precautions during assembly processes.

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

Select this component when a fixed 9 V output is required with high current capability in a small footprint. Consider the HTSOP-J8 package for surface mount applications where thermal dissipation and board space are critical constraints. Ensure input voltage remains within the specified 4 V to 26.5 V range for optimal regulation.

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

This device belongs to the BD90FC0 series of low-saturation regulators from ROHM Semiconductor. It shares architectural similarities with other members like BD90FC0WFP-E2 but differs in packaging, utilizing HTSOP-J8 instead of TO-252-5. The series is categorized under PMIC voltage regulators designed for general-purpose use rather than automotive-grade environments.

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

BD90FC0WFP-E2 offers identical electrical characteristics but uses a TO-252-5 package. BDJ5FC0WEFJ-E2 provides similar functionality in the same HTSOP-J8 package but outputs 15 V. Verify pin compatibility and thermal requirements when substituting.
