MAX6033BAUT25+T

Overview

The MAX6033BAUT25+T is a high-precision series voltage reference featuring a fixed 2.5V output with ±0.2% initial accuracy and a maximum temperature coefficient of 15ppm/°C. It operates within an input voltage range of 2.7V to 12.6V, drawing a typical quiescent supply current of 40µA while sourcing up to 15mA. The device utilizes bandgap technology and laser-trimmed thin-film resistors for stability. It is housed in a miniature 6-pin SOT-23 package and supports operation across the automotive temperature range from -40°C to +125°C.

Feature Summary

• Bandgap architecture with laser-trimmed thin-film resistors ensures excellent initial accuracy and low noise performance.
• Ultra-low dropout voltage capability allows efficient operation even when the input voltage approaches the output level.
• Stable with capacitive loads up to 100µF, simplifying circuit design for transient response improvement.

Applications

• Precision regulators
• High-resolution A/D and D/A converters
• Hard-disk drives
• High-accuracy industrial and process control systems

Procurement Notes

Verify the component against official Analog Devices documentation to confirm the specific suffix indicates RoHS compliance. Ensure the ordering code matches the required output voltage and accuracy grade. Confirm that the SOT-23-6 package footprint aligns with the target PCB layout requirements before finalizing procurement.

Selection Notes

Select this part when a fixed 2.5V reference with moderate precision is required in a compact form factor. The device is suitable for applications where power consumption must be minimized due to its low quiescent current. Verify that the input voltage remains within the specified operating range to maintain regulation and avoid excessive dropout.

Part Context

This component belongs to the MAX6033 family of ultra-high-precision series voltage references manufactured by Analog Devices / Maxim Integrated. The family offers various output voltages and accuracy grades, all sharing the same low-power, low-dropout characteristics and SOT-23-6 packaging format designed for space-constrained electronics.

Replacement Considerations

Compatible alternatives within the same family include MAX6033AAUT25+T for higher accuracy or MAX6033CAUT25+T for different temperature coefficient specifications. Cross-referencing pinouts and electrical parameters with the original datasheet is essential to ensure functional equivalence.
