MAX6101EUR+T

Overview

The MAX6101EUR+T is a low-cost, micropower, low-dropout voltage reference from the MAX6100–MAX6107 family. It provides a fixed output voltage of 1.25V with an initial accuracy of ±0.4% and a maximum temperature coefficient of 75ppm/°C. The device operates over an extended temperature range of -40°C to +85°C and accepts input voltages from 2.5V to 12.6V. It draws a quiescent supply current of 90µA (max 125µA) and can source up to 5mA or sink 2mA of load current. Packaged in a compact 3-pin SOT-23 format, it eliminates the need for external compensation capacitors.

Feature Summary

• Features proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Offers ultra-low dropout performance and supply-independent quiescent current for battery efficiency.
• Eliminates the requirement for external output capacitors while maintaining stability with capacitive loads.

Applications

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

Procurement Notes

Verify the specific suffix 'EUR+T' corresponds to the tape-and-reel packaging variant within the SOT-23-3 package. Confirm that the ordering increment requirements align with your procurement volume needs. Ensure the component meets RoHS compliance standards as indicated by the '+' designation in the part number.

Selection Notes

Select this component when a fixed 1.25V reference is required in space-constrained designs. It is suitable for applications demanding low power consumption and high accuracy without the board area penalty of external compensation components. Consider the input voltage range limits relative to the system's supply rails.

Part Context

This part belongs to the MAX6100–MAX6107 series of series-mode voltage references manufactured by Analog Devices / Maxim Integrated. The series shares common architectural features including micropower operation and SOT-23 packaging, differentiated primarily by their fixed output voltage options ranging from 1.25V to 5V.

Replacement Considerations

Other members of the MAX6100–MAX6107 family share identical pinouts and functional characteristics but offer different fixed output voltages. Verify that the alternative part number matches the required 1.25V output specification before substitution.
