Procurement Notes

Verify the specific suffix 'PWR' confirms the 8-TSSOP package and tape-and-reel packaging format. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the order quantity aligns with standard reel sizes if bulk procurement is required. Check for any recent Product Change Notifications regarding manufacturing site or material changes.

Selection Notes

Select this component when a fixed 1.235 V reference is required with tight tolerance and low drift. The ±1% accuracy makes it suitable for applications demanding higher precision than standard LM385 variants. Consider the 8-TSSOP package for automated surface-mount assembly processes. Evaluate the 20 mA maximum current capability against the circuit's load requirements.

Part Context

This part belongs to the LM385 family of micropower shunt voltage references from Texas Instruments. It shares functional similarities with other LM385 variants but offers improved accuracy and lower temperature drift compared to standard versions. The device utilizes bandgap reference technology to maintain stability over temperature variations.
