MIC2810-4MSYML-TR

Overview

The MIC2810-4MSYML-TR is a triple-output power management IC from Microchip Technology, integrating one 2MHz step-down (buck) converter and two low-dropout (LDO) linear regulators. It operates within an input voltage range of 1.65V to 5.5V and supports surface mount installation in a 16-MLF® (4x4mm) package. The device provides three distinct output configurations: Output 1 delivers 1.2V at 600mA via the buck converter; Output 2 supplies 1.8V at 300mA; and Output 3 provides 3.3V at 300mA. It functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-frequency 2MHz switching regulator with two independent LDOs for compact design
• Includes LowQ mode functionality to minimize quiescent current during light load conditions
• Features Power-On Reset (POR) circuitry to ensure system stability upon startup
• Combines switching efficiency with LDO noise performance for sensitive analog loads

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Embedded systems utilizing mixed-signal architectures
• Battery-powered equipment needing efficient power conversion
• Industrial control modules operating in extended temperature ranges

Procurement Notes

Verify the specific suffix 'MSYML' against the official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with the 16-MLF package footprint and thermal pad connection guidelines. Confirm that the 2MHz switching frequency aligns with your electromagnetic interference constraints and passive component selections. Check for any recent Product Change Notifications regarding assembly sites or labeling updates.

Selection Notes

Select this component when a single solution is needed to provide both switched and linear regulation. The integrated buck converter handles higher current demands efficiently, while the LDOs provide clean power for noise-sensitive circuits. Consider the 16-MLF package size for space-constrained layouts. Verify that the input voltage range covers your supply variations and that the output currents meet the peak load requirements of all connected subsystems.
