Procurement Notes

Verify the specific ordering suffix F01TA to confirm the 1% tolerance level and SOT-23 package configuration. Confirm RoHS compliance status as indicated in the datasheet documentation. Ensure the procurement channel is authorized by Diodes Incorporated to avoid unauthorized sales risks. Check for any product change notices (PCN) regarding manufacturing site or assembly updates before finalizing orders.

Selection Notes

Select this component for applications prioritizing space-saving surface mount designs in low-power environments. The low knee current makes it suitable for battery-operated devices where quiescent power consumption must be minimized. Verify that the load requirements fall within the recommended 23 μA to 5 mA operating range for optimal performance. Consider the 1% initial accuracy and temperature coefficient when designing precision analog circuits.
