MIC2225-GJYMT-TR

Overview

The MIC2225-GJYMT-TR is a dual-output voltage regulator featuring a high-efficiency 2MHz PWM synchronous buck converter and a 300mA LDO. It operates from a 2.7V to 5.5V input supply, delivering up to 600mA output current in PWM mode with greater than 95% efficiency. The device includes fully integrated MOSFET switches, micropower shutdown (1mA), thermal shutdown, and current limit protection. It is housed in a 10-pin 2mm x 2mm Thin MLF package and supports fixed output voltages down to 1V.

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
• Features internal power MOSFETs eliminating external inductor requirements for simplified design
• Includes comprehensive protection mechanisms such as thermal shutdown and current limiting

Applications

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

Procurement Notes

Verify the specific suffix GJYMT against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering code matches the required tape-and-reel packaging format. Cross-reference the RoHS status and operating temperature range (-40°C to +125°C) with system requirements before finalizing procurement.

Selection Notes

Select this component when space-constrained portable designs require both a high-current switching regulator and a low-noise linear regulator. The 2MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the load transient response requirements are met by the device's stability with ceramic capacitors.

Part Context

This part belongs to the MIC2225 family of ultra-small dual-channel DC/DC regulators. It combines Micrel/Microchip's synchronous buck technology with an integrated LDO to provide a complete power solution for mobile and handheld devices. The Thin MLF package minimizes PCB footprint while maintaining thermal performance.
