MIC2225-GJYMT

Overview

The MIC2225-GJYMT is a dual-output voltage regulator manufactured by Microchip Technology, formerly Micrel. It integrates a high-efficiency 2MHz PWM synchronous buck (step-down) DC/DC converter and a 300mA Low Dropout (LDO) regulator. The switching regulator accepts an input voltage range of 2.7V to 5.5V and delivers up to 600mA output current with internal power MOSFETs. The device operates at a constant 2MHz frequency in PWM mode and features fully integrated switches. It is housed in a compact 10-pin 2mm x 2mm Thin MLF package and supports a junction temperature range from -40°C to +125°C.

Feature Summary

• Integrates a high-efficiency 2MHz synchronous buck regulator and a 300mA LDO in a single ultra-small package
• Features fully integrated internal power MOSFETs for the DC-DC converter
• Includes micropower shutdown capability and thermal/current limit protection

Applications

• Application processors core and I/O supply rails
• Camera DSP power supplies
• Multimedia chipset power management

Procurement Notes

Verify the specific suffix 'GJYMT' against official Microchip documentation to confirm fixed output voltage options and pinout compatibility. Ensure the component source is authorized to avoid counterfeit parts. Confirm RoHS compliance status as indicated in the datasheet. Check for any recent product lifecycle changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when space-constrained portable designs require both a high-current switching regulator and a low-noise LDO. The 2MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the required output voltage matches the fixed option available in the GJYMT suffix variant. Ensure the load transient requirements are met by the specified stability with ceramic capacitors.

Part Context

This part belongs to the MIC2225 family of dual-output regulators designed for portable electronics. The family typically includes variants with different output voltage configurations and packaging options. Microchip acquired Micrel, so branding may appear as either Micrel or Microchip Technology in legacy documentation. The series is optimized for applications requiring efficient power conversion in minimal board area.

Replacement Considerations

Check for MIC2225 variants with compatible suffixes such as GMYMT or G4YMT if exact pin-to-pin replacement is needed. Verify that alternative packages like TMLF-10 match the footprint. Ensure the replacement maintains the same 2MHz frequency and current capabilities.
