MAX6101EUR-T

Overview

The MAX6101EUR-T is a micropower series voltage reference with a fixed output of 1.25V, housed in a 3-pin SOT-23 package. It operates within an input voltage range of 2.5V to 12.6V and maintains an initial accuracy of ±0.4% maximum. The device features a low temperature coefficient of 75ppm/°C and draws a quiescent supply current of 90µA typical (125µA maximum). It can source up to 5mA and sink up to 2mA of load current while remaining stable without external compensation capacitors.

Feature Summary

• Proprietary curvature-correction circuitry ensures high precision across the operating temperature range
• Laser-trimmed thin-film resistors provide stable initial accuracy and low temperature drift
• Internal frequency compensation eliminates the need for external capacitors, saving board space
• Low dropout design allows operation with minimal headroom between input and output voltages

Applications

• Portable battery-powered systems
• Notebook computers
• PDAs and GPS devices
• Cellular phones
• Hard-disk drives

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the input voltage source can deliver sufficient current during turn-on transients to guarantee reliable startup under all operating conditions.

Selection Notes

Select this part when a fixed 1.25V reference is required in a compact surface-mount footprint. It is suitable for applications demanding low power consumption and high stability over wide temperature variations. Consider the 5mA sourcing capability if driving moderate loads directly without additional amplification stages.

Part Context

This component belongs to the MAX6100–MAX6107 family of low-cost, low-dropout voltage references. All members share identical pinouts, packages, and core electrical characteristics, differing only in their fixed output voltage levels. This family is designed to replace traditional shunt references by eliminating external biasing resistors and reducing overall system power dissipation.

Replacement Considerations

Other members of the MAX6100–MAX6107 family offer different fixed output voltages but maintain identical pin configurations and performance metrics.
