• High initial accuracy of ±1% tolerance
• Operates with up to 20 mA shunt current
• Compact SOT-23-3 surface-mount packaging

Applications

• Precision analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage sources
• Battery-powered instrumentation circuits
• Portable measurement equipment power supplies

Procurement Notes

Verify the specific suffix L-2-5 confirms the 2.5V output variant. Confirm the SOT-23-3 package matches your PCB footprint requirements. Ensure the ±1% accuracy class meets your circuit design specifications before finalizing procurement orders.

Selection Notes

Select this component when a stable 2.5V reference is required in a small form factor. The ±1% accuracy suits general-purpose precision applications. Consider the 20 mA current limit for load driving capabilities. Verify thermal dissipation requirements for the SOT-23-3 package in enclosed designs.

Part Context

This part belongs to the SPX385 series of micropower voltage references from MaxLinear. The series includes various output voltages and packages. The AM-L-2-5 variant specifically denotes the 2.5V output in the SOT-23-3 package, distinguishing it from other voltage options like 1.2V or 2.048V in different housings.

Replacement Considerations

Check for direct pin-compatible substitutes offering similar 2.5V output and ±1% accuracy. Verify that alternative components support the 20 mA current range and fit the SOT-23-3 footprint. Ensure temperature coefficients match application needs.
