MAX6065AEUR-T

Overview

The MAX6065AEUR-T is a precision, micropower, low-dropout voltage reference providing a fixed 5V output. It features an initial accuracy of ±0.2% and a maximum temperature coefficient of 20ppm/°C. The device operates within an input voltage range of VOUT + 0.2V to 12.6V and draws a typical quiescent supply current of 90µA. It can source up to 5mA or sink 2mA of load current. The unit is housed in a 3-pin SOT-23 package and functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Proprietary curvature-correction circuit with laser-trimmed thin-film resistors for high stability
• Internally compensated design that eliminates the need for external compensation capacitors
• Supply current virtually independent of input voltage variations
• Capable of sourcing 5mA and sinking 2mA without requiring external biasing resistors

Applications

• Analog-to-Digital Converters (ADCs)
• Portable battery-powered systems
• Precision 3V/5V systems

Procurement Notes

Verify the specific 'A' grade suffix ensures the required ±0.2% initial accuracy specification. Confirm the 'EUR' designation matches the intended SOT-23 surface-mount footprint requirements. Ensure the '+T' tape-and-reel packaging aligns with automated assembly processes. Cross-reference the manufacturer's latest documentation for any potential product lifecycle changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a stable 5V reference is needed in space-constrained designs. The internal compensation allows for board area savings by removing external capacitors. The low dropout characteristic supports operation near minimum input voltages. Verify that the 5mA sourcing capability meets the peak load demands of the target application circuitry.

Part Context

This part belongs to the MAX6061–MAX6068 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The series utilizes BiCMOS technology and includes various fixed output voltage options ranging from 1.25V to 5V. All members share common architectural features such as micropower consumption and low-dropout performance within the same compact package form factor.

Replacement Considerations

The MAX6065BEUR-T serves as a direct functional substitute within the same package, offering a relaxed ±0.4% initial accuracy tolerance while maintaining identical electrical characteristics and pin configurations.
