MIC94305YMT-TR

Overview

The MIC94305YMT-TR is a 500mA integrated load switch incorporating Ripple Blocker™ active filter technology. It operates within an input voltage range of 1.8V to 3.6V, delivering a maximum output current of 0.5A. The device features a low dropout voltage of 200mV at full load and maintains high accuracy with typical line regulation of 0.1% and load regulation of 10mV. Designed for surface-mount applications, it utilizes a compact 6-pin TDFN package (1.6x1.6mm). The component supports an operating temperature range from -40°C to +125°C and includes thermal protection and current limit features.

Feature Summary

• Integrates Ripple Blocker™ active filter technology to suppress high-frequency noise on the power rail
• Provides precise voltage regulation with minimal dropout under full load conditions
• Includes built-in thermal protection and current limiting for enhanced system reliability

Applications

• Noise-sensitive analog circuits requiring clean power supplies

Procurement Notes

Verify the specific suffix and package type against the manufacturer's latest datasheet to ensure compatibility with your design. Confirm that the Ripple Blocker™ feature aligns with your noise suppression needs. Check for any end-of-life notices or alternative recommendations from Microchip Technology before finalizing procurement plans.

Selection Notes

Select this component when high-frequency ripple attenuation is critical alongside standard load switching functions. Ensure the input voltage stays within the 1.8V to 3.6V range. Consider the 6-pin TDFN footprint constraints during PCB layout. Verify that the 500mA current rating meets the peak load demands of the downstream circuitry without exceeding thermal limits.

Part Context

This part belongs to Microchip's Ripple Blocker™ series, designed to combine load switching capabilities with active noise filtering. It addresses challenges in power integrity for sensitive electronics by integrating filtering directly into the power path, reducing the need for external passive components typically required for noise suppression.
