MIC2003-1.2YM5

Overview

The MIC2003-1.2YM5 is a power distribution switch manufactured by Microchip Technology, designed for load driver applications. It features a P-channel output with a maximum current of 1.2A and a typical on-resistance of 70mΩ. The device operates within a load voltage range of 1.8V to 5.5V and utilizes a non-inverting input interface. It provides fault protection through fixed current limiting and over-temperature shutdown. The component is housed in an SOT-23-5 package (SC-74A/SOT-753) and supports surface mount installation across a junction temperature range of -40°C to 125°C.

Feature Summary

• Provides highly efficient noise suppression for sensitive data and image capturing systems
• Integrates fixed current limiting and over-temperature fault protection mechanisms

Applications

• Sensitive data systems requiring noise suppression
• Image capturing systems
• Power distribution networks

Procurement Notes

Verify the specific suffix and revision level when ordering, as availability may vary due to discontinuation status or lifecycle changes. Confirm RoHS compliance requirements against the latest manufacturer documentation, as some sources indicate this specific part number may not be compliant. Ensure the SOT-23-5 footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring low on-resistance and integrated thermal protection in a compact surface-mount package. It is suitable for high-side switching where noise immunity is critical. Compare against the MIC2091 series if lower current ratings are sufficient, noting that the MIC2003 offers higher current capacity at 1.2A. Verify input logic compatibility and voltage ranges for the target system.

Part Context

This part belongs to the MIC2003 family of fixed and adjustable current-limiting power distribution switches originally developed by Micrel Semiconductor, now under Microchip Technology. The MIC2003 series is designed for robust load management in portable and industrial electronics. The YM5 suffix denotes the specific SOT-23-5 packaging configuration used for space-constrained designs.
