MAX1977EEI-TG068

Overview

The MAX1977EEI-TG068 is a linear main power supply controller manufactured by Analog Devices Inc./Maxim Integrated. It features four standard output regulators designed for special purpose applications. The device operates with voltage outputs ranging from 2V to 3.3V and 5V to 5.5V. It is housed in a QSOP-28 surface-mount package, suitable for automated assembly processes.

Feature Summary

• Integrates four independent linear regulators within a single controller unit
• Supports dual voltage ranges for flexible system power distribution
• Designed specifically for specialized power management requirements

Applications

• Special purpose regulator systems
• Multi-rail power supply architectures
• Embedded control units requiring compact linear regulation

Procurement Notes

Verify the exact suffix configuration against official Analog Devices documentation to ensure compatibility with specific thermal and electrical requirements. Confirm package type and operating temperature range match design specifications before procurement.

Selection Notes

Select this component when multiple regulated voltages are required from a single controller interface. Ensure input voltage constraints align with the specified output ranges. Validate thermal performance for the QSOP-28 package under expected load conditions.

Part Context

This part belongs to the Maxim Integrated PMIC family, focusing on integrated linear regulation solutions. It serves as a consolidated alternative to discrete regulator designs, reducing board space and component count in complex power systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX1977 series or newer generations from Analog Devices. Verify that substitute parts maintain identical output configurations and thermal characteristics.
