Current Regulation/Management Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration. Confirm that the component meets AEC-Q100 automotive grade requirements for your target application. Ensure the SOD-123-2 package dimensions align with your PCB layout constraints. Check for any recent product change notifications regarding manufacturing site or material composition updates.

Current Regulation/Management Selection Notes

Select this component when a fixed 20 mA constant current source is required for LED driving. The choice depends on the need for a simple, low-pin-count solution supporting both step-up and step-down voltage conversion. Consider the wide operating temperature range and automotive qualification if deploying in harsh environments. Evaluate the 45 V input limit against your system's maximum supply voltage.

Current Regulation/Management Part Context
