MAX6063BEUR+T

Overview

The MAX6063BEUR+T is a precision, micropower, low-dropout voltage reference featuring a fixed 3.0V output in a 3-pin SOT-23 package. It delivers an initial accuracy of ±0.4% and a maximum temperature coefficient of 30ppm/°C across the -40°C to +85°C range. The device typically draws 90µA of supply current while sourcing up to 5mA or sinking 2mA. It operates with an input voltage range from VOUT + 0.2V to 12.6V and exhibits a maximum dropout voltage of 200mV at a 1mA load.

Feature Summary

• Proprietary curvature-correction circuit ensures high precision and stability
• Laser-trimmed thin-film resistors provide tight initial accuracy limits
• Internally compensated design eliminates the need for external capacitors
• Supply current remains virtually independent of the input voltage level

Applications

• Portable battery-powered systems
• Analog-to-digital converters (ADCs)
• Precision 3V and 5V systems
• PDAs and GPS devices

Procurement Notes

Verify the specific suffix 'B' indicates the ±0.4% accuracy grade rather than the tighter ±0.2% variant. Confirm the '+T' designation corresponds to tape-and-reel packaging as specified in the manufacturer's ordering guide. Ensure the component meets RoHS compliance requirements for your assembly process.

Selection Notes

Select this part when a fixed 3.0V reference is required in space-constrained designs. It serves as a direct alternative to shunt references by eliminating series biasing resistors. The low quiescent current makes it suitable for extending battery life in portable electronics where board area is limited.

Part Context

This component belongs to the MAX6061–MAX6068 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares identical pinouts and core architectures, differing primarily in their factory-trimmed output voltage options and accuracy grades. All members utilize the same compact SOT-23-3 footprint.

Replacement Considerations

MAX6063AEUR+T offers the same 3.0V output with improved ±0.2% accuracy.
