MAX6100EUR+T

Overview

The MAX6100EUR+T is a low-cost, micropower, low-dropout voltage reference in a 3-pin SOT23 package. It provides a fixed 1.8V output with an initial accuracy of ±0.4% and a temperature coefficient of 75ppm/°C. The device operates within a supply voltage range of 2.5V to 12.6V, drawing a quiescent current of 90µA (max 125µA). It can source up to 5mA and sink up to 2mA of load current. The unit functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Proprietary curvature-correction circuitry ensures stable performance over temperature variations.
• Laser-trimmed thin-film resistors provide high initial accuracy without requiring external trimming components.
• Internal compensation eliminates the need for external capacitors, saving board space.
• Supply current remains virtually independent of input voltage changes.

Applications

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

Procurement Notes

Verify that the component matches the specific 1.8V output variant within the MAX6100–MAX6107 family. Confirm the presence of the '+T' suffix indicates tape-and-reel packaging. Ensure the ordering information aligns with the required SOT23-3 package type and the specified operating temperature range.

Selection Notes

Select this part when a fixed 1.8V reference is required in a compact form factor. It is suitable for applications needing low quiescent current and high output drive capability relative to its size. Consider the 75ppm/°C temperature coefficient and ±0.4% initial accuracy against system requirements.
