MAX6133A30

Overview

The MAX6133A30 is a high-precision, low-power series voltage reference manufactured by Analog Devices under the Maxim Integrated brand. It delivers a fixed output of 3V with an initial accuracy of ±0.06% and a temperature coefficient of 7ppm/°C. The device operates within a supply voltage range of 3.2V to 12.6V and draws a maximum supply current of 85µA. It supports a maximum shunt current of 15mA and functions reliably across an extended temperature range from -40°C to +125°C. Noise performance is specified at 24µVp-p (0.1Hz to 10Hz) and 15µVrms (10Hz to 10kHz).

Feature Summary

• Features bandgap technology for low-noise performance and excellent accuracy.
• Utilizes laser-trimmed, high-stability thin-film resistors with post-package trimming.
• Provides load regulation specifications guaranteed for source currents up to 15mA.

Applications

• Precision regulators
• A/D and D/A converters
• Power supplies

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm package integrity and traceability documentation upon receipt. Ensure storage conditions align with semiconductor handling standards to maintain electrical characteristics. Cross-reference ordering suffixes carefully as they may indicate specific packaging variations without altering functional parameters.

Selection Notes

Select this part when system requirements demand high precision with minimal power consumption in portable applications. The low dropout voltage allows operation with tight input-output differentials. Consider the 8-pin uMAX/uSOP package constraints for PCB layout. Evaluate thermal management needs given the wide operating temperature range and self-heating effects under load.

Part Context

This component belongs to the MAX6133 family of precision voltage references designed for communication and portable equipment. It combines tiny packaging with excellent precision performance. The series-mode architecture saves system power compared to shunt references while requiring minimal external components.

Replacement Considerations

Direct substitutes include other MAX6133 variants with different output voltages or accuracy grades, such as MAX6133A25 or MAX6133BASA. Verify pin compatibility and thermal characteristics before substitution.
