Procurement Notes

Verify that the specific part number matches the required Grade A specifications, including the 3.0 V output and ±0.2% accuracy. Confirm the SOT-23-3 package type aligns with the PCB footprint requirements. Ensure the ordering suffix corresponds to the intended reel packaging format. Cross-reference the RoHS compliance status with project environmental standards before finalizing procurement.

Selection Notes

Select this component when a stable 3.0 V reference is needed in a small form factor. The wide input current range allows flexibility in bias resistor selection for varying supply voltages. Consider the thermal hysteresis and noise specifications if the application involves sensitive analog signal paths or rapid temperature cycling environments.

Part Context

This device belongs to the ADR504x family of micropower shunt voltage references, which includes variants with different output voltages such as 2.048 V, 2.5 V, 4.096 V, and 5.0 V. All members share similar architectural features, including pin compatibility and package options, allowing for modular design strategies across different voltage requirements within the same system.

Replacement Considerations

The datasheet explicitly states pin compatibility with LM4040 and LM4050 series devices. Designers should verify electrical parameters against these equivalents to ensure functional interchangeability in existing designs.
