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 5.2V to 12.6V and draws a typical quiescent supply current of 90µA. It can source up to 5mA and sink up to 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

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Eliminates the need for external compensation capacitors while maintaining stability with capacitive loads.
• Offers supply current that remains virtually independent of the supply voltage to maximize efficiency.
• Provides low dropout voltage characteristics suitable for battery-operated systems.

Applications

• Analog-to-Digital Converters (ADCs)
• Portable Battery-Powered Systems
• Precision 3V/5V Systems

Procurement Notes

Verify the specific suffix 'EUR' corresponds to the SOT-23-3 package and reel packaging configuration. Confirm the '+T' designation indicates tape-and-reel delivery. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5V reference is required with high initial accuracy and low power consumption. It is suitable for applications where board space is limited due to the compact SOT-23 package. Consider the 20ppm/°C temperature coefficient for environments with significant thermal variations. Ensure the input voltage stays above the minimum dropout threshold to maintain regulation under all load conditions.

Part Context

This part belongs to the MAX6061–MAX6068 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common internal architectures but varies in output voltage options ranging from 1.25V to 5V. The MAX6065 specifically provides the 5V output option within this series, designed for general-purpose precision applications requiring stable reference voltages.

Replacement Considerations

Compatible substitutes within the same family include MAX6065BEUR+T, which offers slightly lower initial accuracy. Other family members like MAX6061 through MAX6068 share identical pinouts and packages but provide different fixed output voltages. Verify that any replacement maintains the required 5V output and meets the specific accuracy and temperature coefficient needs of the design.
