MAX6035BAUR30+T

Overview

The MAX6035BAUR30+T is a high-voltage, precision micropower voltage reference in a 3-pin SOT23 package. It provides a fixed 3.0V output with an initial accuracy of ±0.5% and a maximum temperature coefficient of 75ppm/°C across the -40°C to +125°C range. The device operates from a supply voltage up to 33V, drawing a typical quiescent current of 73µA. It can source 10mA or sink 2mA of load current without requiring external compensation capacitors.

Feature Summary

• Proprietary curvature-correction circuit for low temperature drift
• Laser-trimmed thin-film resistors ensure high initial accuracy
• Supply-independent operation eliminates external biasing resistors
• Internally compensated design stable with capacitive loads

Applications

• Industrial control loops
• Li-ion battery chargers
• Portable data-acquisition systems
• Low-power test equipment

Procurement Notes

Verify the specific suffix 'B' indicates the 0.5% accuracy grade and 'U' denotes the SOT-23 package. Confirm the '+T' designation corresponds to tape-and-reel packaging. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability.

Selection Notes

Select this model when a 3.0V reference with moderate precision (±0.5%) is sufficient. Choose over the 'A' grade variant if cost reduction is prioritized over tighter accuracy specifications. Consider the wide input voltage range for applications with varying supply rails. Evaluate thermal performance to ensure power dissipation remains within the SOT-23 package limits under maximum load conditions.

Part Context

This component belongs to the MAX6035 series of high-supply-voltage precision voltage references. It serves as a compact upgrade for legacy industry-standard devices like the REF02 and REF43. The series offers reduced package size and significantly lower power consumption compared to older alternatives, making it suitable for space-constrained and battery-operated designs.

Replacement Considerations

Direct replacements include MAX6035AAUR30+T for higher accuracy or MAX6035BAUR25+T/MAX6035BAUR50+T for different voltage outputs. Legacy equivalents such as REF02 or REF43 may require external components and larger footprints.
