Procurement Notes

Verify that the ordering suffix 'TR PBFREE' corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to procurement to ensure adherence to environmental regulations applicable in your region.

Selection Notes

Select this component when circuit design demands minimal quiescent current draw alongside precise low-voltage regulation. Ensure the selected package aligns with the PCB footprint requirements for the DO-35 case outline. Validate that the maximum regulator current specifications meet the load requirements of the target application without exceeding the 500 mW power dissipation limit.
