MIC29510-3.3WT

Overview

The MIC29510-3.3WT is a fixed positive low-dropout (LDO) voltage regulator from the MIC29510 series, manufactured by Microchip Technology. It provides a fixed output voltage of 3.3 V with a maximum output current capability of 5 A. The device utilizes a PNP pass element and features a typical dropout voltage of 0.7 V at full load, with a maximum specified dropout of 1 V. It operates within an input voltage range of 6 V to 8 V and supports a junction temperature range from -40 °C to +125 °C. The unit is housed in a TO-220 SIP-3 package.

Feature Summary

• High-current regulation capability up to 5 A using Super Beta PNP process technology
• Fast transient recovery response to input voltage surges and output load changes
• Comprehensive protection against overcurrent faults, reversed polarity, and overtemperature conditions

Applications

• Systems requiring high-current stable power rails
• Battery operated instrumentation
• Communications equipment power management

Procurement Notes

Verify the specific suffix 'WT' corresponds to the TO-220 SIP-3 through-hole package configuration as documented in official Microchip datasheets. Confirm that the fixed 3.3 V output variant matches the application requirements, as the MIC29510 family also includes adjustable versions. Ensure compliance with RoHS standards if required by the target assembly process.

Selection Notes

Select this component when a robust 5 A LDO solution is needed for applications tolerant of linear regulation losses. The TO-220 package facilitates thermal dissipation for high-current operation. Verify that the minimum input voltage requirement of approximately 4 V above the output is met by the system supply to ensure proper regulation and dropout performance under all operating conditions.

Part Context

The MIC29510 series represents a line of high-performance LDO regulators designed for demanding power management tasks. Manufactured originally by Micrel and now part of Microchip Technology, these devices are known for their fast transient response and high accuracy. The MIC29510-3.3WT specifically denotes the fixed 3.3 V output version in a through-hole package, distinguishing it from surface-mount or adjustable variants within the same functional family.
