MAX6431CIUS

Overview

The MAX6431CIUS is a fixed-output low-dropout (LDO) linear regulator manufactured by Analog Devices Inc. and Maxim Integrated. It provides a preset output voltage of 2.5V with an accuracy of ±2.0% over the operating temperature range. The device delivers up to 300mA of load current while consuming only 82µA of supply current. It features a fully integrated microprocessor reset circuit with four timeout options, ensuring reliable system startup. The component operates within an input voltage range of 2.7V to 5.5V and is available in a compact UCSP-6 package.

Feature Summary

Integrated microprocessor reset circuit with selectable timeout options
Low quiescent current consumption for battery-powered applications
Fixed output voltage with high precision across temperature ranges
Compact UCSP-6 surface-mount packaging

Applications

Battery-powered portable equipment
Microprocessor power supply systems
Embedded control circuits requiring reset functionality
Medical sensors and monitoring devices

Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature grade (-40°C to +85°C). Confirm the 'C' prefix denotes commercial availability status if required. Ensure the UCSP-6 package matches your PCB footprint requirements. Check RoHS compliance documentation for environmental regulations. Validate that the fixed 2.5V output meets your system voltage specifications before procurement.

Selection Notes

Select this component when a fixed 2.5V output is required alongside integrated reset functionality. Consider the 300mA current limit for load requirements. Evaluate the UCSP-6 package size against board space constraints. Compare quiescent current needs against other LDO families if ultra-low power is critical. Ensure input voltage remains within the 2.7V to 5.5V operational window.

Part Context

The MAX6431 belongs to the MAX6469–MAX6484 family of low-dropout linear regulators with integrated microprocessor reset circuits. These devices are designed for portable electronics where space and power efficiency are paramount. The family offers various preset output voltages from 1.5V to 3.3V. The MAX6431 specifically provides the 2.5V option with industrial temperature grading.
