Voltage Reference Procurement Notes

Verify the specific suffix 'X' indicates reel packaging when ordering. Confirm the 'NOPB' designation ensures lead-free compliance and RoHS adherence. Ensure the selected variant matches the required 2.0V output and SOT-23 package dimensions. Cross-reference the full part number with official Texas Instruments documentation to confirm availability and manufacturing status before procurement.

Voltage Reference Selection Notes

Select this component when a fixed 2.0V reference is required with ±0.2% initial accuracy. Consider the 50 ppm/°C temperature coefficient for thermal stability needs. The SOT-23-3 package is ideal for space-limited PCB designs. Ensure the circuit design accommodates the 15 mA maximum shunt current and 103 µA minimum operating current requirements for proper regulation.

Voltage Reference Part Context

This part belongs to the LM4050 series of precision micropower shunt voltage references. The series offers various fixed output voltages and accuracy grades. The LM4050 family is characterized by its low noise, small footprint, and wide operating temperature range, making it suitable for diverse electronic applications requiring reliable voltage referencing.

Voltage Reference Replacement Considerations

Compatible substitutes include other LM4050 variants with different output voltages or accuracy grades, such as LM4050BEM3X-2.5/NOPB or LM4050BEM3X-5.0/NOPB, provided the voltage requirement differs. Direct replacements must maintain the SOT-23-3 package and similar electrical characteristics.
