MAX6025AEUR+T

Overview

The MAX6025AEUR+T is a precision, low-power, low-dropout series-mode voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.5V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 15ppm/°C. The device operates within an input voltage range of 2.7V to 12.6V and draws a quiescent supply current of 35μA maximum. It supports source and sink currents up to 500μA with a dropout voltage of 100mV at full load. Packaged in a compact SOT-23-3 surface-mount format, it functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision
• Series-mode topology eliminates the need for external biasing resistors required by shunt references
• Internally compensated design ensures stability with capacitive loads up to 2.2nF without external components

Applications

• Hand-held equipment
• Data acquisition systems
• Industrial and process-control systems
• Battery-operated equipment
• Hard-disk drives

Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when sourcing. Confirm the 'A' grade designation corresponds to the tighter 0.2% initial accuracy specification rather than the standard B grade. Ensure the manufacturer is identified as Analog Devices or Maxim Integrated to guarantee authenticity. Check for RoHS compliance markings on the reel documentation.

Selection Notes

Select this component when a stable 2.5V reference is required in space-constrained designs utilizing the SOT-23-3 package. It is suitable for applications demanding low quiescent current to extend battery life. Consider the 500μA drive capability for moderate load requirements. Verify that the input voltage remains above the minimum dropout threshold relative to the 2.5V output under all operating conditions.

Part Context

This part belongs to the MAX6012/MAX6021/MAX6025 family of micropower voltage references. These devices share identical pinouts and physical dimensions but differ in output voltage levels and specific electrical characteristics. The MAX6025 variant specifically targets the 2.5V output requirement within this miniature form factor lineup.

Replacement Considerations

The TSM6025AEUR+ is documented as a pin-for-pin alternate source for the MAX6025. Verify compatibility regarding temperature coefficients and noise specifications before substitution.
