MIC2821-4GMSYML-TR

Overview

The MIC2821-4GMSYML-TR is a power management integrated circuit manufactured by Microchip Technology. It integrates a single DC/DC switching regulator with three independent Low Dropout (LDO) regulators. The device features independent enable controls for each regulator output, allowing for flexible power sequencing and management. It is housed in a 16-pin MLF package and is designed for surface mount technology applications.

Feature Summary

• Integrates one switching voltage converter and three LDOs
• Provides independent enable control for each regulator channel
• Supports digital triple LDO configuration

Applications

• Portable electronic devices requiring multiple voltage rails
• Embedded systems with mixed analog and digital power needs
• Industrial control modules needing regulated power supplies

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and temperature grade. Confirm RoHS compliance status through official datasheets or manufacturer declarations before integration. Check moisture sensitivity levels and reflow soldering profiles during assembly planning. Ensure supply chain authenticity by sourcing from authorized distributors only.

Selection Notes

Select this component when a compact solution combining switching efficiency and LDO precision is required. Evaluate input voltage ranges against system requirements. Consider thermal performance in the MLF package for high-current applications. Verify that independent enable functionality aligns with system power-up sequences.

Part Context

This part belongs to Microchip's PMIC family, specifically designed for power management in space-constrained environments. It replaces discrete regulator solutions by integrating multiple functions into a single chip, reducing board space and component count while maintaining regulatory performance standards.

Replacement Considerations

Consult Microchip documentation for direct pin-to-pin replacements or functional equivalents within the MIC2821 series. Verify compatibility of enable logic and output configurations before substitution.
