Procurement Notes
Verify the specific suffix 'F03' confirms the SOT-23 package and ±3% tolerance before procurement. Confirm that the ordering information matches the required reel size and tape width specifications. Ensure compatibility with the intended operating current range of 20μA to 5mA for optimal performance.
Selection Notes
Select this component when space-saving is critical due to its small outline SOT-23 package. Choose this part for applications requiring a precise 2.5V reference with low power consumption. Consider the ±3% tolerance if higher precision variants like F01 or F02 are not necessary for the specific circuit requirements.
