MAX6001EUR-T

Overview

The MAX6001EUR-T is a micropower, low-dropout series voltage reference from the MAX6001–MAX6005 family. It provides a fixed output voltage of 1.25V with a maximum initial accuracy of 1% and a temperature coefficient of 100ppm/°C. The device operates within a supply voltage range of 2.5V to 12.6V and draws a quiescent supply current of up to 45µA. It features ±400µA output source and sink current capability with a dropout voltage of 100mV at 400µA load. The component is housed in a SOT-23-3 package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Eliminates the need for external resistors or compensation capacitors through internal design.
• Offers supply current that remains virtually independent of the input supply voltage.
• Capable of sourcing and sinking up to 400µA while maintaining stability with zero output capacitance.

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 ordering suffix against the manufacturer's official documentation to confirm the exact electrical grade and packaging configuration. Ensure the selected variant matches the required output voltage and tolerance specifications for the target application. Cross-reference the part number with the latest datasheet revision history to account for any updates in manufacturing or testing standards.

Selection Notes

Select this component for applications requiring low power dissipation and wide variations in supply voltage. The device is suitable for space-critical designs due to its compact SOT-23-3 package and lack of requirement for external components. Consider the 100mV dropout voltage when designing for minimum supply conditions.

Part Context

This component belongs to the MAX6001–MAX6005 family of low-cost, low-power, low-dropout voltage references. These devices combine the cost advantages of shunt references with the power-saving benefits of series references. The family includes variants with different fixed output voltages, all sharing similar electrical characteristics and pin configurations.

Replacement Considerations

Other members of the MAX6001–MAX6005 family may serve as substitutes if the output voltage requirements differ. Verify compatibility regarding package type, operating temperature range, and electrical performance parameters before implementation.

FAQ

Does the MAX6001EUR-T 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 an external compensation capacitor.

How does the supply current behave relative to the input voltage?

The quiescent supply current is virtually independent of the supply voltage, exhibiting only a minimal variation of 0.8µA/V with changes in VIN.
