MAX6063BEUR-T

Overview

The MAX6063BEUR-T is a precision, micropower, low-dropout voltage reference from the MAX6061–MAX6068 series. It provides a fixed output voltage of 3.0V with an initial accuracy of ±0.4% and a maximum temperature coefficient of 30ppm/°C. The device operates within an extended temperature range of -40°C to +85°C and features a quiescent supply current of typically 90µA. It can source up to 5mA or sink 2mA of load current while maintaining stability without requiring an external compensation capacitor.

Feature Summary

• Proprietary curvature-correction circuit and laser-trimmed thin-film resistors ensure high precision and low temperature drift.
• Series-mode architecture eliminates the need for external biasing resistors and reduces power waste compared to shunt references.
• Internally compensated design allows operation without external capacitors, saving board space in compact applications.
• Stable with capacitive loads and capable of sourcing significant load currents suitable for driving ADCs and other sensitive circuits.

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 'B' grade corresponds to the required ±0.4% initial accuracy specification. Ensure the input voltage source can provide sufficient current during turn-on transients if operating near minimum dropout conditions. Check for any recent product change notices regarding pinout or marking updates.

Selection Notes

Select this part when a stable 3.0V reference is needed in a small SOT23-3 package. Choose the 'B' grade variant if ±0.4% accuracy meets system requirements, offering a balance between performance and cost. Consider the MAX6063AEUR-T if tighter ±0.2% accuracy is necessary. Evaluate the 90µA quiescent current against battery life requirements for portable designs.
