Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Microchip Technology, as Micrel was previously acquired. Ensure the MSOP-10 package type matches the design requirements. Check for moisture sensitivity labeling on the reel. Validate that the 300mA output current meets the system load demands before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a compact synchronous buck solution with low quiescent current. The 1MHz switching frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. The adjustable output voltage provides flexibility for various logic levels. Consider the thermal performance in the MSOP-10 package under full load conditions at elevated temperatures.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MIC2203 series of DC-DC converters. It is functionally similar to the MIC2203YMM but differs in packaging format. The MIC2204 offers higher current capacity, while the MIC2203 focuses on moderate current with high efficiency. It serves as a power management IC for portable electronics requiring stable voltage regulation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

MIC2203YMM is a tube-packaged equivalent with identical electrical specifications. MIC2204YMM offers double the output current (600mA) with a 2MHz switching frequency. Verify pin compatibility and thermal characteristics when substituting these variants.
