TC1303A-ZI0EUN

Overview

The TC1303A-ZI0EUN 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 maximum input voltage rating of 6 V. The device operates with a quiescent current of approximately 25 µA per channel and maintains a typical dropout voltage of 200 mV at full load. Integrated protection mechanisms include thermal shutdown and current limiting to ensure reliable operation under fault conditions.

Feature Summary

• Dual independent LDO channels for simultaneous power supply generation
• Integrated thermal shutdown and current limit protection circuits
• Low quiescent current consumption for efficient battery-powered applications

Applications

• Portable consumer electronics requiring multiple voltage rails
• Battery-operated devices needing efficient power management
• Embedded systems requiring stable low-noise voltage regulation

Procurement Notes

Verify the specific suffix 'ZI0EUN' against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint and reflow soldering profile requirements before procurement.

Selection Notes

Select this component when dual independent 500 mA outputs are required within a 6 V input constraint. Consider its low quiescent current for battery life optimization and verify that the thermal performance meets your system's ambient temperature requirements.

Part Context

This part belongs to Microchip's TC1303 series of dual LDO regulators. It is designed for space-constrained applications requiring two regulated outputs from a single package, offering a compact solution compared to using separate single-channel regulators.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Ensure any replacement matches the dual-channel architecture, 500 mA output capability, and 6 V max input rating.
