MAX8632ETI+

Overview

The MAX8632ETI+ is a dual low-dropout linear regulator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features two independent adjustable output channels capable of delivering up to 300 mA each. The device operates within an input voltage range of 1.8 V to 5.5 V and provides outputs adjustable from 0.8 V to 5.0 V. It utilizes a pin-programmable architecture for output voltage selection, eliminating the need for external feedback resistors. The component is housed in an 8-lead TDFN package with exposed pad, measuring 3 mm x 3 mm. It includes integrated protection mechanisms such as thermal shutdown and current limiting.

Feature Summary

• Dual independent adjustable output channels with 300 mA drive capability
• Pin-programmable architecture for simplified design and reduced component count
• Integrated thermal shutdown and current limiting for system protection
• Compact 3 mm x 3 mm TDFN package with exposed thermal pad

Applications

• Portable battery-powered consumer electronics
• Wireless communication modules requiring stable low-noise power
• Embedded systems with multiple voltage rails
• IoT devices with space-constrained PCB layouts

Procurement Notes

Verify the exact suffix and tape/reel specifications against the official datasheet before ordering. Confirm availability status as distribution channels may list obsolete or limited-stock items. Ensure the supplier provides valid traceability documentation. Cross-reference the manufacturer part number with the specific package variant to avoid mismatches in lead time and pricing structures.

Selection Notes

Select this component when a compact dual LDO solution is required for portable applications. The pin-programmable feature reduces board space compared to resistor-divider designs. Verify that the required output voltages align with the available pin configurations. Consider the thermal performance of the TDFN package relative to the expected load current and ambient temperature conditions.

Part Context

This part belongs to the MAX863x family of dual low-dropout regulators designed for high-efficiency power management in mobile devices. It complements other Maxim Integrated PMIC solutions by providing dedicated analog and digital supply rails. The family emphasizes low quiescent current and small footprint to support modern miniaturization trends in electronic hardware design.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX863x series. Verify if newer generations offer improved efficiency or extended operating temperatures. Ensure any substitute maintains the same package dimensions and electrical characteristics for seamless integration.
