MIC2811-4GJLYML-TR

Overview

The MIC2811-4GJLYML-TR is a high-performance Power Management IC (PMIC) from Microchip Technology, designed to support four output voltage rails with maximum efficiency. It integrates a single DC/DC converter and three Low Dropout (LDO) regulators. The device operates within an input voltage range of 2.7 V to 5.5 V and features a low noise bypass mode. Packaged in a 16-lead MLF (4x4 mm) surface-mount case, it supports digital power management applications requiring compact solutions.

Feature Summary

• Integrates one switching DC/DC converter and three LDO regulators for multi-rail power distribution
• Features low noise bypass capability for sensitive analog circuitry
• Supports digital control interfaces for programmable power management

Applications

• Handheld mobile devices
• Portable consumer electronics
• Embedded systems requiring efficient multi-voltage regulation

Procurement Notes

Verify the complete part number including the -TR suffix for tape-and-reel packaging. Confirm the GJLYML package code corresponds to the 16-MLF (4x4 mm) footprint required by your PCB layout. Ensure compatibility with the 2.7 V to 5.5 V input supply range for your specific application design.

Selection Notes

Select this component when a single IC solution is needed to generate multiple voltage rails efficiently. It is suitable for designs prioritizing board space reduction through integrated PMIC architectures. Consider the thermal performance of the exposed pad MLF package for heat dissipation requirements in dense layouts.

Part Context

This part belongs to the MIC2811/2821 family of high-performance PMICs. These devices are engineered to replace discrete regulator solutions, offering improved efficiency and reduced component count. The family targets applications demanding reliable power management in portable and industrial environments.

Replacement Considerations

Check for direct substitutes within the MIC2811 series or compatible Microchip PMIC families. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
