MAX6029EUK33+T

Overview

The MAX6029EUK33+T is a micropower, low-dropout bandgap voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 3.3V with an initial accuracy of ±0.15% and a maximum temperature coefficient of 30ppm/°C. The device operates within a supply voltage range of 3.5V to 12.6V and draws a maximum supply current of 7.25µA. It features a low dropout voltage of 200mV at 4mA source current and can source up to 4mA while sinking up to 1mA. The component is housed in a miniature 5-pin SOT-23 package and is specified for operation over the extended temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low power consumption with minimal supply current draw
• High precision stability with tight initial accuracy and low drift
• Capable of sourcing significant load current with low dropout voltage
• Internal compensation ensures stability without external capacitors

Applications

• Battery-powered systems
• Hand-held instruments
• Precision power supplies
• A/D and D/A converters

Procurement Notes

Verify the specific suffix 'EUK33' confirms the 3.3V output voltage variant. Ensure the '+T' designation matches the required tape-and-reel packaging format. Confirm RoHS compliance status if environmental regulations apply to the assembly process. Check for any lead-free markings on the physical component or documentation.

Selection Notes

Select this component when a stable 3.3V reference is needed in space-constrained designs. It is suitable for applications requiring low quiescent current to extend battery life. Consider the 30ppm/°C temperature coefficient for precision requirements across the industrial temperature range. Verify input voltage stays above the minimum threshold to maintain regulation.

Part Context

This part belongs to the MAX6029 family of ultra-low-power precision series voltage references. The family includes variants with different fixed output voltages such as 2.048V, 2.5V, 3V, 4.096V, and 5V. These devices share common characteristics including low dropout, high accuracy, and miniature packaging options like SOT-23 and SO packages.

Replacement Considerations

Other MAX6029 variants with different output voltages (e.g., MAX6029EUK30+T for 3V) may be considered if voltage levels differ. Cross-reference with other Maxim series references if pin compatibility or package size constraints require alternative solutions.
