MAX6102EUR-T

Overview

The MAX6102EUR-T is a series-mode voltage reference providing a fixed 2.5V output. It operates within an input voltage range of (VOUT + 0.2V) to 12.6V and draws a maximum quiescent supply current of 125µA. The device delivers up to 5mA sourcing and 2mA sinking load current with a maximum initial accuracy of ±0.4% and a temperature coefficient of 75ppm/°C. It features low dropout characteristics, reaching 50mV at 1mA source current, and maintains stability without requiring external compensation capacitors.

Feature Summary

• Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors ensures high precision and low temperature drift.
• Series-mode architecture eliminates the need for external biasing resistors and reduces power waste compared to shunt references.
• Internally compensated design allows stable operation with any capacitive load when sourcing less than 200µA, saving board space.

Applications

• Portable Battery-Powered Systems
• Notebook Computers
• PDAs, GPSs, DMMs
• Cellular Phones
• Hard-Disk Drives

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and reel specifications. Confirm RoHS compliance status as indicated in the latest datasheet revision. Ensure the input voltage source can provide sufficient current during turn-on transients to guarantee reliable startup under all operating conditions.

Selection Notes

Select this component for applications requiring a fixed 2.5V reference with micropower consumption and high accuracy. Consider the 75ppm/°C temperature coefficient and ±0.4% initial tolerance for precision requirements. Evaluate the 5mA source capability against load demands and ensure the input voltage remains above the minimum dropout threshold for optimal regulation.

Part Context

This part belongs to the MAX6100–MAX6107 family of low-cost, micropower, low-dropout voltage references manufactured by Maxim Integrated. These devices share common architectural features including proprietary curvature correction and SOT23 packaging, differing primarily in their fixed output voltage options ranging from 1.25V to 5V.

Replacement Considerations

Other members of the MAX6100–MAX6107 family offer different fixed output voltages but share identical pinouts and electrical characteristics. Verify that alternative parts match the required output voltage and package configuration before substitution.

FAQ
