MIC2205-1.5YML-TR

Voltage Regulators - DC DC Switching Regulators Overview

The MIC2205-1.5YML-TR is a synchronous buck switching regulator IC from Microchip Technology, housed in a 10-VFDFN exposed pad package. It provides a fixed positive output voltage of 1.5V with a maximum load current capability of 600mA. The device operates within an input voltage range of 2.7V to 5.5V and features a fixed switching frequency of 2MHz. Designed for high efficiency, it includes built-in low Q-mode functionality to optimize performance under light loads.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous rectification architecture for enhanced conversion efficiency
• Fixed 1.5V output voltage configuration eliminating external feedback resistors
• Integrated low Q-mode operation to improve light-load power savings
• Compact 10-pin VFDFN package design suitable for space-constrained PCB layouts

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered consumer electronics requiring stable 1.5V logic rails
• Embedded systems utilizing microcontrollers or digital signal processors
• Industrial control modules operating within standard single-supply voltage ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'YML-TR' confirms the 10-VFDFN package and tape-and-reel shipping format. Ensure compatibility with 1.5V fixed output requirements rather than adjustable variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration into final assemblies.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.5V output is required without external programming resistors. The 600mA current rating suits moderate load applications, while the 2MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider thermal dissipation requirements given the exposed pad thermal management needs of the DFN package.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MIC2205 family of synchronous buck regulators, which also includes adjustable versions and different current ratings such as the MIC22205 series. Unlike the MIC2250 boost regulator, this device steps down voltage. It serves as a compact power solution for modern low-voltage digital circuits requiring efficient regulation from common battery sources.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other MIC2205 variants with different fixed voltages (e.g., MIC2205-3.3YML-TR) if voltage levels differ. Cross-reference with similar 600mA synchronous buck regulators from other manufacturers ensuring compatible pinouts and thermal characteristics.
