Voltage Reference Procurement Notes

Verify the manufacturer designation, as this specific part number may be associated with Texas Instruments or Maxim Integrated depending on the supply chain history. Confirm the package type matches the required SC-70 footprint and ensure the 0.2% accuracy grade meets the design specifications before procurement.

Voltage Reference Selection Notes

Select this component when a small form factor is required alongside high precision. The SC-70 package offers significant size reduction compared to SOT-23 alternatives. Ensure the application can accommodate the specified shunt current limits and that the 50ppm/°C temperature stability aligns with system requirements.

Voltage Reference Part Context

This component belongs to the LM4050/LM4051 family of two-terminal shunt voltage references. The series is characterized by its subminiature packaging options and low power consumption, making it suitable for applications where board space and energy efficiency are critical constraints.

Voltage Reference Replacement Considerations
