MIC2225-G4YMT-TR

Overview

The MIC2225-G4YMT-TR is a dual-output voltage regulator from Microchip Technology, featuring a high-efficiency 2MHz PWM synchronous buck converter and a 300mA LDO. It operates with an input voltage range of 2.7V to 5.5V and delivers up to 600mA output current in PWM mode. The device is housed in a 10-pin 2mm x 2mm Thin MLF package and supports a junction temperature range from –40°C to +125°C.

Feature Summary

• Integrates a 2MHz synchronous buck regulator and a 300mA LDO for compact dual-rail power solutions
• Provides ultra-low noise performance suitable for sensitive analog and digital loads
• Includes internal power MOSFETs with thermal shutdown and current limit protection

Applications

• Application processor core and I/O supply rails
• Camera DSP power management
• Multimedia chipset power distribution

Procurement Notes

Verify the specific suffix G4YMT against the official datasheet to confirm fixed output voltage settings and pinout compatibility. Ensure the ordering code matches the required reel quantity and RoHS compliance status as defined by Microchip Technology. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when space-constrained designs require both switching efficiency and low-noise linear regulation. The integrated solution reduces external component count compared to discrete alternatives. Verify that the required output voltages align with the fixed options available for the G4YMT suffix variant.

Part Context

This part belongs to the MIC2225 family of ultra-small dual-channel DC/DC regulators. It is designed for portable applications requiring high efficiency and minimal footprint. The Thin MLF package enables dense PCB layouts while maintaining thermal performance within the specified operating temperature range.

Replacement Considerations

Check for MIC2225-GMYMT TR or MIC2225-GJYMT TR if different fixed output voltages are needed. Ensure substitute parts maintain the same 10-pin Thin MLF package and electrical characteristics.
