MAX6025BEUR-T

Overview

The MAX6025BEUR-T is a precision, low-power, low-dropout series-mode voltage reference housed in a miniature SOT23-3 surface-mount package. It provides a fixed output voltage of 2.5V with an initial accuracy of ±0.4% and a maximum temperature coefficient of 30ppm/°C over the -40°C to +85°C operating range. The device draws a quiescent supply current of 35μA maximum and supports up to ±500μA of load source/sink current. It operates within an input voltage range from VOUT + 0.2V to 12.6V, featuring a dropout voltage of 200mV at 500μA load.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision
• Internally compensated design eliminates the need for external compensation capacitors
• Capable of sourcing and sinking up to 500μA of load current while maintaining stability
• Series-mode architecture ensures supply current remains virtually independent of input voltage

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 ordering. Confirm that the 'B' grade designation aligns with the required ±0.4% initial accuracy specification for your application. Ensure the input voltage source can provide sufficient current during turn-on transients to guarantee reliable operation.

Selection Notes

Select this component when a stable 2.5V reference is required in space-constrained designs utilizing SOT23-3 packages. It is suitable for applications demanding low power consumption without the efficiency penalties associated with shunt-mode references. Consider the ±500μA drive capability if the reference must directly interface with low-impedance loads or ADC inputs.

Part Context

This part belongs to the MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/MAX6045/MAX6050 family of precision voltage references. All members share identical pinouts, package types, and core architectural features, differing primarily in their fixed output voltage levels ranging from 1.247V to 5.000V.

Replacement Considerations

The TSM6025AEUR+ is documented as a pin-for-pin alternate source for the MAX6025 series. Verify electrical parameter compatibility, particularly regarding temperature coefficients and accuracy grades, before substituting.
