MAX6033CAUT50#G16

Overview

The MAX6033CAUT50#G16 is an ultra-high-precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 5V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 40ppm/°C over the -40°C to +125°C automotive temperature range. The device operates within an input voltage range of 5.2V to 12.6V, consuming a typical quiescent supply current of 40µA while sourcing up to 15mA. It features low dropout voltage, excellent load regulation, and stability with capacitive loads.

Feature Summary

• Ultra-high precision bandgap technology with laser-trimmed thin-film resistors
• Stable operation with capacitive loads up to 100µF
• Low quiescent supply current for extended battery life
• Miniature 6-pin SOT23 surface-mount package

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated by the suffix. Ensure the specific lot matches the required automotive temperature grade (-40°C to +125°C). Check for any obsolescence notices or product change notifications prior to final procurement decisions.

Selection Notes

Select this part when a stable 5V reference is required in space-constrained designs. The SOT23-6 package minimizes board area compared to larger packages. Consider the 40ppm/°C drift specification against application thermal requirements. Verify that the input voltage remains above the minimum dropout threshold during all operating conditions.

Part Context

This component belongs to the MAX6033 family of high-precision, low-dropout series voltage references. The CAUT50 designation indicates the C grade (±0.1% accuracy), U temperature range, T tape-and-reel packaging, and 5V output. The #G16 suffix denotes RoHS-compliant packaging. These devices utilize BiCMOS processes for low noise and high stability.
