MAX6037AAUK25

Overview

The MAX6037AAUK25 is a low-power, fixed series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a stable output voltage of 2.5 V with an initial accuracy of ±0.2%. The device features a temperature coefficient of 6 ppm/°C and operates within an input voltage range up to 5.5 V. It draws a typical operating supply current of 280 µA and supports a maximum shunt current of 5 mA. The component is housed in a compact SOT-23-5 surface-mount package and functions reliably across a wide temperature range from -40°C to +125°C.

Feature Summary

• Low-dropout micropower architecture for energy-efficient operation
• High precision with 0.2% initial accuracy and low temperature drift
• Compact SOT-23-5 surface-mount packaging for space-constrained designs

Applications

• Portable battery-powered instrumentation
• Data acquisition systems requiring stable reference voltages
• Handheld meters and test equipment

Procurement Notes

Verify the specific suffix (e.g., +T) for packaging configuration such as reel or cut tape when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure compatibility with the target PCB footprint for the SOT-23-5 package. Cross-reference the exact part number with the latest datasheet to confirm electrical parameters match system requirements.

Selection Notes

Select this component when a precise 2.5 V reference is required in low-power applications. The 6 ppm/°C temperature coefficient ensures stability across industrial temperature ranges. Consider the 280 µA quiescent current for battery life calculations. The SOT-23-5 package is suitable for dense board layouts. Verify that the 5.5 V maximum input voltage aligns with the system supply rails.

Part Context

The MAX6037 family includes various fixed and adjustable voltage options ranging from 1.184 V to 5 V. This specific model represents the 2.5 V fixed output variant within the low-power series reference line. It shares architectural similarities with other members of the MAX6037 series but differs in output voltage and potentially in temperature coefficient specifications depending on the grade.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6037 family offering different voltage outputs if system requirements change. Verify that any substitute maintains the same SOT-23-5 footprint and electrical characteristics, particularly the 0.2% accuracy and 6 ppm/°C drift.
