Voltage Reference Procurement Notes
Verify the specific suffix 'X' against official Texas Instruments documentation to confirm tape-and-reel packaging specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the exact part number with the manufacturer's latest datasheet to validate electrical parameters and pinout configurations before integration.
Voltage Reference Selection Notes
Select this component when a compact SOT-23-5 footprint is required alongside moderate precision levels. The 0.5% initial accuracy and 100 ppm/°C temperature coefficient suit general-purpose applications where ultra-high precision is not critical. Consider the 60 µA quiescent current for battery life optimization in portable electronics.
