MIC29510-5.0WT

Overview

The MIC29510-5.0WT is a fixed positive low-dropout (LDO) voltage regulator manufactured by Microchip Technology, formerly Micrel. It provides a stable 5.0 V output with a maximum current capacity of 5 A. The device features a typical dropout voltage of 0.7 V and a maximum of 1.0 V at full load. It operates within an input voltage range of 6 V to 8 V, with an absolute maximum rating of 20 V. Line regulation is specified at 0.025%, and load regulation at 0.05%. The component is housed in a TO-220 SIP-3 package and supports junction temperatures from -40°C to +125°C.

Feature Summary

• Utilizes Super Beta PNP process for high-current performance and fast transient recovery
• Integrated protection against overcurrent faults, reversed polarity, and overtemperature conditions

Applications

• High-current power supply systems requiring precise voltage regulation
• Industrial equipment power distribution networks
• Embedded systems needing robust LDO regulation under heavy loads

Procurement Notes

Verify the manufacturer designation as Micrel or Microchip Technology on the datasheet, as both names appear in public records for this part number. Confirm the specific suffix 'WT' corresponds to the TO-220 SIP-3 through-hole package. Ensure the fixed 5.0 V output variant is selected, distinct from the adjustable MIC29512 model. Cross-reference the JESD-30 code R-XSFM-T3 for accurate package identification during sourcing.

Selection Notes

Select this component when a fixed 5 V output is required with up to 5 A continuous current capability. It is suitable for applications demanding low dropout characteristics and high accuracy. Consider the thermal management requirements due to the high current handling. Verify that the input voltage stays within the 6 V to 8 V operational window to ensure proper regulation and avoid exceeding the 20 V absolute maximum rating.

Part Context

This regulator belongs to the MIC29510/29512 family of high-current, high-accuracy LDOs. These devices are designed for applications requiring fast response to input surges and load changes. The MIC29510 is the three-pin fixed-output version, while the MIC29512 offers adjustable output. Both utilize proprietary Super Beta PNP technology for enhanced performance compared to standard bipolar regulators.
