MIC29510-5.0BT

Overview

The MIC29510-5.0BT is a fixed positive low-dropout (LDO) linear regulator providing a stable 5V output with a maximum current capacity of 5A. It utilizes a PNP pass element and features a nominal dropout voltage of 0.7V, with a maximum specified at 1V. The device supports an absolute maximum input voltage of 20V, operating within a range of 6V to 8V for standard applications. It includes one functional regulator with a single output channel housed in a TO-220 SIP3 package. Line regulation is rated at 0.025% and load regulation at 0.05%. The component operates within a junction temperature range up to 125°C.

Feature Summary

• Utilizes proprietary Super Beta PNP process for high-current performance and fast transient recovery from input surges and load changes.
• Comprehensive protection against overcurrent faults, reversed input polarity, reversed lead insertion, overtemperature conditions, and voltage transients.
• Features a TTL-compatible enable control pin for external on/off switching functionality.

Applications

• High-current digital logic power supplies
• Power distribution networks requiring fast transient response
• Battery-powered instrumentation systems

Procurement Notes

Verify the specific suffix 'BT' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives if required by the application, as indicated in component parameters. Cross-reference the supplier's documentation with Microchip Technology's latest release notes to confirm availability and manufacturing status before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5V output is required with high current capability up to 5A. Consider the TO-220 package for through-hole mounting and thermal dissipation needs. Evaluate the 0.7V typical dropout voltage against the minimum input voltage requirements of the system. Ensure the design accommodates the necessary heat sinking for operation at maximum load currents within the specified temperature range.

Part Context

This part belongs to the MIC29510/29512 series of high-accuracy, low-dropout voltage regulators manufactured by Micrel, now part of Microchip Technology. The series distinguishes between fixed output versions like the MIC29510 and adjustable output variants such as the MIC29512. These regulators are designed for applications demanding robust performance and integrated protection features in a compact form factor.

Replacement Considerations

Consult official substitution lists for equivalent LDO regulators with matching 5A current ratings and 5V fixed outputs. Verify that alternative components support similar dropout characteristics and protection mechanisms. Ensure pin compatibility and thermal performance align with the existing TO-220 footprint constraints.
