TC1303B-ZH0EMFTR

Overview

The TC1303B-ZH0EMFTR is a dual low-dropout (LDO) voltage regulator manufactured by Microchip Technology. It features two independent output channels capable of delivering up to 500 mA each, with a typical dropout voltage of 250 mV at full load. The device operates from an input voltage range of 2.7 V to 5.5 V and provides fixed output voltages of 3.3 V and 1.8 V. It incorporates built-in thermal shutdown and current limit protection mechanisms to ensure reliable operation under fault conditions.

Feature Summary

• Dual independent LDO channels for simultaneous power rail generation
• Low dropout voltage performance ensures efficient regulation near input limits
• Integrated thermal shutdown and current limiting for enhanced system protection

Applications

• Portable consumer electronics requiring multiple stable voltage rails
• Embedded systems needing compact dual-output power solutions
• Battery-powered devices utilizing low-voltage digital logic components

Procurement Notes

Verify the specific suffix 'ZH0EMFTR' against official Microchip documentation to confirm tape-and-reel packaging and lead-free status. Ensure the ordering part number matches the required output voltages and package type. Cross-reference with authorized distributors to validate authenticity and avoid counterfeit components. Confirm compliance with RoHS directives if applicable to your manufacturing process.

Selection Notes

Select this component when dual independent outputs are required in a small footprint. Consider the 500 mA per channel capability and the specific 3.3 V/1.8 V fixed outputs. Evaluate the dropout characteristics against your minimum input voltage requirements. Verify that the thermal management capabilities align with your expected operating environment and load profiles.

Part Context

This part belongs to Microchip's TC1303 family of dual LDO regulators. It is designed for applications requiring two separate regulated voltages from a single package. The family offers various output voltage combinations and package options to suit different design constraints while maintaining consistent performance characteristics across the series.

Replacement Considerations

Consult Microchip's official cross-reference tools for direct replacements. Verify pin compatibility and electrical specifications before substituting. Ensure any alternative component meets the same dual-channel requirement and output voltage specifications.
