MAX6033CAUT30#G16

Overview

The MAX6033CAUT30#G16 is a high-precision series voltage reference featuring a 3.000V output, ±0.1% initial accuracy, and a maximum temperature coefficient of 40ppm/°C. It operates within an input voltage range of 3.2V to 12.6V, consuming a typical quiescent current of 40µA while sourcing up to 15mA. The device exhibits low dropout voltage (max 0.4V at 10mA) and low noise (24µVP-P from 0.1Hz to 10Hz). Packaged in a miniature SOT-23-6, it functions reliably across the automotive temperature range of -40°C to +125°C.

Feature Summary

• Ultra-high precision bandgap architecture with laser-trimmed thin-film resistors for excellent initial accuracy
• Stable operation with capacitive loads up to 100µF without oscillation
• Low quiescent supply current optimized for battery-powered applications
• Miniature 6-pin SOT-23 package design for space-constrained PCB layouts

Applications

• Precision regulators and power supplies
• High-resolution A/D and D/A converters
• Hard-disk drive control circuits
• High-accuracy industrial and process control systems
• Hand-held instruments and portable devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status indicated by the # suffix. Ensure storage conditions maintain moisture sensitivity level integrity prior to soldering. Validate pin configuration against standard SOT-23-6 land patterns during assembly planning.

Selection Notes

Select this variant when a 3.000V fixed output is required with moderate precision specifications. Consider the 40ppm/°C temperature coefficient for applications where thermal stability is critical but ultra-low drift is not mandatory. Evaluate input voltage headroom against the specified dropout characteristics to ensure regulation under minimum load conditions.
