MAX6105EUR+T

Overview

The MAX6105EUR+T is a three-terminal series voltage reference providing a fixed 5.000V output. It operates within an input voltage range of (VOUT + 0.2V) to 12.6V and delivers up to 5mA sourcing current and 2mA sinking current. The device features ±0.4% initial accuracy, a maximum temperature coefficient of 75ppm/°C, and a quiescent supply current of 125µA maximum. It functions over an extended temperature range from -40°C to +85°C in a compact SOT-23-3 package.

Feature Summary

• Proprietary curvature-correction circuit with laser-trimmed thin-film resistors for high precision
• Low dropout design allowing operation at minimal input-to-output voltage differentials
• Micropower architecture with supply current virtually independent of input voltage
• Stable with capacitive loads without requiring external compensation components

Applications

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

Procurement Notes

Verify the specific suffix 'EUR' corresponds to the standard tape-and-reel packaging format intended for automated assembly. Confirm that the '+T' designation aligns with the required environmental compliance standards for the target region. Ensure the ordering increment requirements match the manufacturing specifications for the SOT-23 package type.

Selection Notes

Select this component when a fixed 5V reference is required with low power consumption and high accuracy. The device is suitable for space-constrained designs due to its small footprint. Consider the input voltage headroom requirements relative to the load current to ensure stable operation within the specified dropout limits.

Part Context

This part belongs to the MAX6100–MAX6107 family of low-cost, micropower, low-dropout voltage references. The family offers various fixed output voltages ranging from 1.25V to 5V, all sharing common performance characteristics such as low temperature drift and high output current capability in a tiny 3-pin SOT23 package.

Replacement Considerations

Other members of the MAX6100–MAX6107 family share identical pinouts and electrical characteristics except for the fixed output voltage. Verify that the alternative part number provides the exact 5.000V output required for the application.
