MAX6034BEXR25+T

Overview

The MAX6034BEXR25+T is a precision series voltage reference from the MAX6034 family, manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.5V with an initial accuracy of ±0.4% and a maximum temperature coefficient of 75ppm/°C. The device operates within an input voltage range of 2.7V to 5.5V and draws a typical quiescent supply current of 115µA. It features a low dropout voltage of 200mV at a 1mA load current and is stable with capacitive loads up to 1µF without requiring external compensation components.

Feature Summary

• Proprietary curvature-correction circuitry combined with laser-trimmed thin-film resistors ensures high precision and stability across temperature variations.
• Micropower architecture delivers ultra-low supply current that remains virtually independent of the input supply voltage.
• Low dropout capability allows operation in low-voltage environments while maintaining regulation under load.
• Internal frequency compensation eliminates the need for external capacitors, supporting stable performance with capacitive loads up to 1µF.

Applications

• Hand-Held Equipment
• Data-Acquisition Systems
• Industrial and Process Control Systems
• Battery-Operated Equipment
• Hard-Disk Drives

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix matches the required electrical tolerances and package type. Ensure compliance with RoHS directives and check for any regional distribution restrictions before finalizing procurement plans.

Selection Notes

Select this part when a compact SC-70 package is required alongside precise voltage referencing. The B-grade variant offers ±0.4% accuracy suitable for general-purpose applications where tighter tolerances are not critical. Consider the micropower consumption for battery-operated designs requiring extended operational life.

Part Context

This component belongs to the MAX6034 family of precision, micropower, low-dropout series voltage references. The family includes variants with different output voltages and accuracy grades (A and B), all sharing the same miniature 3-pin SC-70 surface-mount package and core architectural features designed for space-constrained and power-sensitive applications.

Replacement Considerations

Other members of the MAX6034 family, such as MAX6034AEXR25+T, offer higher accuracy but may differ in cost and availability. Cross-referencing with other Maxim Integrated series references requires verifying pin compatibility and electrical specifications against the specific application requirements.
