Voltage Reference Procurement Notes
Verify the complete part number including suffixes such as NOPB for lead-free compliance. Confirm the specific package variant matches design requirements. Ensure thermal management aligns with the specified operating temperature range. Cross-reference datasheet electrical characteristics against system constraints before finalizing procurement decisions.
Voltage Reference Selection Notes
Select this component when space-constrained designs require high-precision references. The adjustable feature allows flexibility for various voltage rails. Verify that the load current remains within the 60 µA to 12 mA operational window. Consider the 50 ppm/°C temperature coefficient for thermal stability requirements in the target environment.
Voltage Reference Part Context
This device belongs to the LM4051-N series of micropower shunt voltage references. It shares architectural similarities with fixed-voltage variants like the LM4050 series but offers programmable output. The SOT-23-3 packaging ensures compatibility with standard surface-mount assembly processes used in compact electronic devices.
