MAX6005EUR-T

Overview

The MAX6005EUR-T is a micropower, low-dropout series voltage reference from Analog Devices Inc./Maxim Integrated, housed in a SOT23-3 package. It provides a fixed output voltage of 5.0V with a maximum initial accuracy of 1% and a temperature coefficient of 100ppm/°C. The device operates within an input voltage range of VOUT + 0.2V to 12.6V and draws a quiescent supply current of up to 45µA. It features internal compensation, ensuring stability with capacitive loads from 0 to 2.2nF without external components.

Feature Summary

• Eliminates the need for external biasing resistors by functioning as a series reference rather than a shunt type.
• Internally compensated design ensures stability across a wide range of capacitive loads without requiring additional components.
• Supply current remains virtually independent of input voltage variations, maximizing efficiency in battery-powered systems.
• Capable of sourcing and sinking up to 400µA while maintaining low dropout voltage characteristics.

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required by assembly equipment. Confirm the '+T' designation aligns with lead-free and RoHS compliance standards mandated by your manufacturing process. Ensure the SOT23-3 footprint matches your PCB layout constraints. Cross-reference the top mark 'FZCZ' to validate authenticity against official manufacturer markings.

Selection Notes

Select this component when a fixed 5.0V reference is required in space-constrained designs. It is suitable for applications needing low power dissipation where supply voltage varies significantly. Consider the 100ppm/°C temperature coefficient for thermal stability requirements. Evaluate the 45µA quiescent current against total system power budgets for battery-operated devices.

Part Context

This part belongs to the MAX6001–MAX6005 family of low-cost, low-power voltage references. All members share identical pinouts, packages, and general electrical behaviors, differing only in their fixed output voltage levels. The MAX6005 specifically targets 5.0V applications within this series, offering the same form factor and performance metrics as its lower-voltage counterparts.

Replacement Considerations

Other members of the MAX6001–MAX6005 family are pin-compatible but provide different fixed output voltages. Verify that the 5.0V output is strictly required before substituting with other variants in the series.

FAQ

Does the MAX6005 require an external capacitor for stability?

No, the device is internally compensated and stable with capacitive loads ranging from 0 to 2.2nF, eliminating the need for external compensation capacitors.

How does the supply current behave with respect to input voltage changes?

The quiescent supply current is virtually independent of the supply voltage, varying by only 0.8µA/V over the operating range.

What is the maximum output current capability?

The device can source and sink up to 400µA of output current.
