Procurement Notes
Verify the specific suffix ME2 to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status through official datasheets. Check for functional safety support classification if required for automotive integration. Ensure ordering quantities align with manufacturer minimums. Validate lead times directly with authorized distributors as production schedules vary.
Selection Notes
Select this component when a fixed 3.3V rail is required with up to 2A continuous current. Consider its low IQ feature for battery-powered or energy-efficient automotive subsystems. Evaluate the HTSSOP-B24 package for thermal management requirements. Compare against other ROHM buck converters if variable output voltages or higher current capacities are needed.
Part Context
This part belongs to ROHM's automotive-grade DC/DC converter portfolio designed for reliable operation in harsh environments. It complements other BD99 series regulators offering different voltage outputs or current capabilities. The product line emphasizes miniaturization and efficiency to support modern vehicle electronics trends.
Replacement Considerations
Consult official substitution guides for equivalent ROHM parts with matching pinouts and electrical characteristics. Verify that alternative components meet the same AEC-Q100 reliability standards. Ensure thermal performance and control loop stability remain compatible with existing board designs.
