MAX6065BEUR+T

Overview

The MAX6065BEUR+T is a precision, micropower, low-dropout voltage reference featuring a fixed 5V output. It operates within an input voltage range of 5.2V to 12.6V and delivers up to 5mA sourcing current with 2mA sinking capability. The device exhibits ±0.4% initial accuracy and a maximum temperature coefficient of 30ppm/°C across the -40°C to +85°C extended temperature range. Quiescent supply current is typically 90µA, ensuring high efficiency in battery-powered applications.

Feature Summary

• Proprietary curvature-correction circuitry combined with laser-trimmed thin-film resistors ensures high precision and stability.
• Series-mode architecture eliminates the need for external biasing resistors required by conventional shunt references.
• Internally compensated design removes the requirement for external compensation capacitors, saving board space.
• Stable operation with capacitive loads allows flexibility in application circuit design.

Applications

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

Procurement Notes

Verify the specific suffix 'B' indicates the ±0.4% accuracy grade rather than the tighter ±0.2% 'A' grade. Confirm the '+T' designation corresponds to tape-and-reel packaging. Ensure the component matches the SOT-23-3 package outline and lead configuration before integration into the bill of materials.

Selection Notes

Select this part when a fixed 5V reference is required with moderate precision and high output drive capability. The series topology offers superior efficiency compared to shunt references by eliminating wasted supply current through series resistors. Consider the dropout voltage characteristics relative to the minimum available supply voltage in the target system.

Part Context
