MAX6029EUK50+T

Overview

The MAX6029EUK50+T is a micropower, low-dropout bandgap voltage reference providing a fixed 5.0V output in a 5-pin SOT-23 package. It features an initial accuracy of ±0.15% and a maximum temperature coefficient of 30ppm/°C. The device operates with a supply voltage range of 5.2V to 12.6V and draws a maximum supply current of 10.5µA. It sources up to 4mA and sinks up to 1mA of load current, maintaining stability with capacitive loads up to 10µF without requiring external compensation.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• High precision with ±0.15% initial accuracy and 30ppm/°C temperature coefficient
• Internal compensation ensures stability with large capacitive loads

Applications

• Battery-Powered Systems
• Hand-Held Instruments
• Precision Power Supplies
• A/D and D/A Converters

Procurement Notes

Verify the specific part number MAX6029EUK50+T against official manufacturer documentation to confirm the 5.0V output voltage and SOT-23-5 package configuration. Ensure compliance with RoHS standards as indicated by the + suffix. Cross-reference electrical specifications such as the 10.5µA maximum supply current and 30ppm/°C temperature coefficient with the latest datasheet revision to guarantee design compatibility.

Selection Notes

Select this component when a stable 5.0V reference is required in space-constrained designs utilizing the SOT-23 form factor. It is appropriate for applications demanding low quiescent current to extend battery life while maintaining high accuracy over the -40°C to +85°C temperature range. Consider the 200mV dropout voltage and 4mA sourcing capability when designing the power supply interface.

Part Context

The MAX6029 series includes multiple output voltages (2.048V, 2.5V, 3V, 3.3V, 4.096V, and 5V) available in both 5-pin SOT-23 and 8-pin SO packages. The EUK50 variant specifically denotes the 5.0V output version in the miniature SOT-23 package. All variants share common characteristics including ultra-low supply current and internal compensation, designed to replace larger SO-package references.

Replacement Considerations

Direct pin-compatible replacements within the same family include MAX6029EUK41+T (4.096V) or MAX6029EUK33+T (3.3V) if different voltage levels are acceptable. For alternative packages, the MAX6029ESA series offers the same functionality in an 8-pin SO format.
