Procurement Notes

Verify the specific suffix 'F' confirms the SOT-23-3 surface mount package configuration. Confirm the '01' designation corresponds to the required ±1% tolerance level for your application. Ensure the ordering code matches the manufacturer's standard reel quantity specifications. Cross-reference the datasheet revision to confirm all electrical characteristics align with your design requirements.

Selection Notes

Select this component when space-saving surface mount packaging is required alongside high precision. The low knee current makes it suitable for low-power designs where quiescent current must be minimized. Verify that the operating environment stays within the specified industrial temperature limits. Consider the fast transient response if the input voltage experiences rapid fluctuations.
