MAX6033AAUT50#TG16

Overview

The MAX6033AAUT50#TG16 is a high-precision series voltage reference with a fixed 5.000V output, ±0.04% initial accuracy, and a maximum temperature coefficient of 10ppm/°C over the -40°C to +125°C range. It operates from an input voltage of 5.2V to 12.6V, draws a typical quiescent current of 40µA, and sources up to 15mA. The device features low dropout voltage (max 200mV), low noise (40µVP-P at 0.1Hz to 10Hz), and excellent load regulation (0.003mV/mA). Packaged in a miniature SOT-23-6 surface-mount format.

Feature Summary

• Ultra-high precision achieved through laser-trimmed thin-film resistors and post-package trimming for ±0.04% initial accuracy.
• Low power consumption with typically 40µA supply current that remains virtually independent of the input voltage.
• Stable operation with capacitive loads up to 100µF, eliminating the need for external series isolation resistors.

Applications

• High-resolution analog-to-digital and digital-to-analog converters
• Precision regulators and power supplies
• Hard-disk drives
• High-accuracy industrial and process control systems

Procurement Notes

Verify the specific suffix #TG16 against the manufacturer's latest documentation to confirm RoHS compliance status and lead-free specifications. Confirm package marking codes match ABDI for this exact part number variant. Ensure the input voltage source can provide sufficient current during turn-on transients to guarantee reliable startup.

Selection Notes

Select this component when system design requires minimal supply current combined with ultra-low temperature drift and high initial accuracy. The SOT-23-6 package is suitable for space-constrained applications. Verify that the minimum input voltage requirement of 5.2V aligns with the available supply rails and that the 15mA output current capability meets the reference load demands.
