MAX6029ESA25+T

Overview

The MAX6029ESA25+T is a micropower, low-dropout bandgap voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.5V with an initial accuracy of ±0.15% and a maximum temperature coefficient of 30ppm/°C. The device operates within a supply voltage range of 2.7V to 12.6V and draws a maximum supply current of 5.75µA. It features a dropout voltage of 200mV at 4mA source current and can source up to 4mA while sinking up to 1mA. The component is housed in an 8-pin SO 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 suitable for battery-operated systems
• High precision performance characterized by tight initial accuracy and low temperature drift
• Capable of sourcing significant load current while maintaining stability under varying conditions
• Designed for compact integration without requiring external compensation capacitors

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm the package type and output voltage configuration. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Confirm availability status as distribution channels may report limited stock or restricted sales regions. Cross-reference the manufacturer part number with official datasheets to validate pin configurations and electrical specifications before procurement.

Selection Notes

Select this component when a stable, precise voltage reference is required in space-constrained designs. The 8-pin SO package offers a balance between board space efficiency and thermal dissipation capabilities compared to smaller packages. Consider the input voltage range and load current requirements to ensure the device operates within its specified dropout and current sourcing limits. Verify that the operating temperature range aligns with the environmental conditions of the target application.

Part Context

The MAX6029 series includes multiple output voltage options and package variants, such as the 5-pin SOT23 and 8-pin SO. The ESA25 variant specifically denotes the 8-pin SO package with a 2.5V output. This family is designed to replace larger, less efficient references in portable electronics. The series maintains consistent electrical characteristics across different output voltages, allowing for design flexibility while preserving the ultra-low power profile.

Replacement Considerations

Direct replacements within the MAX6029 family include other output voltage variants like MAX6029ESA41+ for 4.096V. For package changes, the MAX6029EUK25+T offers the same electrical performance in a 5-pin SOT23 package. Ensure compatibility with existing PCB footprints when selecting alternative package types.
