MAX6005EUR+T

Overview

The MAX6005EUR+T is a micropower, low-dropout series voltage reference in a SOT-23-3 package. It provides a fixed 5V output with ±1% initial accuracy and a maximum temperature coefficient of 100ppm/°C. The device operates within an input voltage range from VOUT + 0.2V to 12.6V. Quiescent supply current is maximized at 45µA, with a variation of only 0.8µA/V relative to the supply voltage. It supports ±400µA source/sink currents and remains stable with capacitive loads up to 2.2nF without external compensation.

Feature Summary

• Eliminates the need for external biasing resistors by functioning as a series-mode reference with supply current virtually independent of input voltage.
• Internally compensated design ensures stability with capacitive loads ranging from 0 to 2.2nF, saving board space in critical applications.
• Offers low dropout voltage characteristics allowing operation in low-voltage systems while maintaining high efficiency over wide supply ranges.

Applications

• Portable and battery-powered equipment
• Notebook computers
• PDAs, GPSs, and digital multimeters (DMMs)
• Cellular phones and pagers
• Hard-disk drives

Procurement Notes

Verify the specific suffix 'EUR+T' corresponds to the tape-and-reel packaging format and lead-free compliance status required for your assembly process. Confirm that the operating temperature range of -40°C to +85°C aligns with your environmental specifications. Ensure the input voltage source can provide sufficient current during turn-on transients to guarantee reliable startup behavior.

Selection Notes

Select this component when a fixed 5V reference is required in space-constrained designs utilizing the SOT-23-3 footprint. It is suitable for applications demanding low power dissipation where supply voltage varies significantly. Consider the internal compensation benefits if minimizing external passive components is a priority. Evaluate the 400µA load capability against your system's peak current requirements.

Part Context

This device belongs to the MAX6001–MAX6005 family of low-cost, low-power voltage references manufactured by Analog Devices / Maxim Integrated. The family shares identical pinouts and general electrical characteristics, differing primarily in their fixed output voltage levels. The MAX6005 specifically targets 5V applications within this series.

Replacement Considerations

Other members of the MAX6001–MAX6005 family share the same package and pin configuration but offer different fixed output voltages. Verify that alternative part numbers match the required 5V output specification before substitution.
