MAX6034AEXR25

Overview

The MAX6034AEXR25+T is a precision micropower low-dropout voltage reference IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a fixed output voltage of 2.5V with an initial accuracy of ±0.2%. The device operates within an input voltage range of 2.7V to 5.5V and draws a supply current of 125µA. It is housed in a compact SC-70-3 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides high-precision voltage regulation with tight initial accuracy tolerances for sensitive analog circuits.
• Features micropower consumption characteristics suitable for battery-operated applications.
• Utilizes a low-dropout architecture allowing operation with minimal input-to-output voltage differentials.

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-powered measurement systems
• Data acquisition systems

Procurement Notes

Verify the specific suffix (+T) indicates reel packaging when sourcing. Confirm the 'A' grade designation matches the required ±0.2% accuracy specification. Ensure the manufacturer is identified as Analog Devices or Maxim Integrated, as legacy branding may vary across distributor listings. Cross-reference the full part number against official datasheets to confirm pinout compatibility.

Selection Notes

Select this component when a fixed 2.5V reference is required in space-constrained designs. The SC-70-3 package offers a small footprint compared to larger alternatives. Consider the 125µA quiescent current for power budget calculations. Verify that the input voltage remains above the dropout threshold throughout the entire operating cycle.

Part Context

This component belongs to the MAX6034 series of micropower voltage references. The series includes various output voltage options and accuracy grades. The 'A' suffix typically denotes tighter initial accuracy specifications compared to standard grades. The 'EXR' indicates the SC-70-3 surface-mount package type.

Replacement Considerations

Check for direct substitutes within the MAX6034 family offering different output voltages if system requirements change. Verify pinout compatibility before replacing with other SC-70-3 voltage references from different manufacturers.
