MAX6029ESA25+

Overview

The MAX6029ESA25+T is a micropower, low-dropout bandgap voltage reference in an 8-pin SO package. It provides a fixed 2.5V output with ±0.15% initial accuracy and a maximum temperature coefficient of 30ppm/°C. The device operates on a supply voltage range of 2.7V to 12.6V while consuming a maximum supply current of 5.75µA. It sources up to 4mA and sinks up to 1mA of load current, featuring a low dropout voltage of 200mV at full source current. Internal compensation ensures stability with capacitive loads up to 10µF without external components.

Feature Summary

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm pinout compatibility and electrical tolerances. Ensure the ordering code matches the required package type and output voltage variant. Confirm RoHS compliance status if environmental regulations apply to the target assembly process.

Selection Notes

Select this component when board space is constrained but higher current drive than SOT23 variants is needed. The 8-pin SO package offers a balance between footprint reduction and thermal performance compared to larger packages. Verify that the input voltage remains within the specified range to maintain regulation and minimize dropout effects during operation.
