Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS status during procurement. Confirm the 'IM5X' designation corresponds to the correct SOT-23-5 tape and reel packaging configuration. Ensure the component meets the required operating temperature range specifications for the intended application environment before finalizing orders.

Voltage Reference Selection Notes

Select this component when a fixed 5 V reference with 0.5% initial accuracy is required. Consider the 50 PPM/°C temperature coefficient for thermal stability needs. The SOT-23 package is ideal for compact PCB layouts. Verify that the 5 mA maximum shunt current capability aligns with the circuit's load requirements.

Voltage Reference Part Context

This part belongs to the LM4120 series of micropower shunt voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The 'IM5X' variant specifically denotes the industrial temperature grade and SOT-23 package type, while 'NOPB' signifies non-phosphorus lead-free construction.

Voltage Reference Replacement Considerations

Check for direct substitutes within the LM4120 family offering different output voltages or accuracies. Verify pin compatibility and electrical characteristics against alternative voltage reference ICs from other manufacturers if sourcing constraints exist.
