Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for Product Change Notifications (PCN) regarding manufacturing updates. Ensure the SOIC-8 package matches design requirements and validate that the fixed 2.85 V output aligns with target circuit specifications before procurement.

Selection Notes

Select this component when a stable 2.85 V supply is required for SCSI-5 interfaces. Consider the 800 mA current capability and 15 V maximum input rating against system demands. Evaluate thermal performance within the 0°C to +125°C range and ensure the SOIC-8 footprint fits the printed circuit board layout constraints.
