MIC29710-5.0BT

Overview

The MIC29710-5.0BT is a fixed-output low-dropout voltage regulator manufactured by Microchip Technology, designed for high-current applications. It provides a stable 5.0V output with a maximum current capability of 7.5A. The device features a dropout voltage of 700mV at full load and maintains precise output tolerance within 2%. It operates over an extended temperature range from 0°C to +125°C and utilizes a TO-220-5 package for through-hole mounting. Input voltage ranges from 2.25V to 16V, supporting efficient power conversion in demanding electronic systems.

Feature Summary

• Utilizes proprietary Super ßeta PNP process for fast transient response and low ground current
• Comprehensive protection against overcurrent faults, reversed polarity, and overtemperature conditions
• TTL-compatible enable pin allows external on/off control or continuous operation

Applications

• Intel Pentium and Pentium Plus processor power supplies
• High-efficiency linear power systems
• Post-regulators for switching power supplies
• Battery-powered equipment requiring low dropout voltage

Procurement Notes

Verify the specific suffix BT indicates the TO-220-5 package configuration when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the fixed 5.0V output requirement. Cross-reference datasheet revisions to confirm thermal performance specifications align with system design constraints before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high current delivery with minimal voltage drop under heavy loads. The fixed 5.0V output simplifies design compared to adjustable variants. Consider the TO-220-5 package for adequate thermal dissipation in high-power scenarios. Verify input voltage stability remains within the specified 2.25V to 16V range to ensure proper regulation and protection functionality activation.

Part Context

This regulator belongs to the MIC29710/2 series, which are high-current, high-accuracy LDOs featuring rapid transient recovery. The MIC29710 variant specifically offers a fixed output voltage, contrasting with the adjustable MIC29712. Both share identical protection features and utilize the same Super ßeta PNP technology for superior performance in demanding power management environments.

Replacement Considerations

MIC29710-3.3BT serves as a direct substitute for applications requiring a 3.3V fixed output instead of 5.0V. MIC29712BT is the adjustable counterpart within the same family, offering flexible voltage setting capabilities while maintaining identical current and protection specifications.
