L7824

Overview

The L7824 is a positive linear voltage regulator IC from the L78xx series, manufactured by Lumimax Optoelectronic Technology. It provides a fixed 24 V output with a maximum output current of 1.5 A. The device operates within an input voltage range up to 40 V and features a TO-220 package with three pins. It includes internal protections against overload and thermal shutdown.

Feature Summary

• Provides stable positive voltage regulation for electronic circuits
• Integrated thermal overload protection safeguards against overheating
• Fixed output voltage eliminates need for external feedback components

Applications

• Industrial control systems requiring stable power supplies
• General-purpose electronics power conditioning
• Battery-powered equipment voltage stabilization

Procurement Notes

Verify manufacturer authenticity as Lumimax Optoelectronic Technology may distribute third-party L78xx components. Confirm package type matches design requirements. Check datasheet for specific electrical tolerances and thermal characteristics before integration into final products.

Selection Notes

Select this component when a fixed 24 V supply is needed with moderate current demands. Ensure input voltage does not exceed 40 V to prevent damage. Consider thermal management solutions due to linear regulation heat dissipation in high differential voltage scenarios.

Part Context

Part of the widely used L78xx family of three-terminal linear regulators. This series offers reliable performance for basic voltage regulation tasks across various industries. The L7824 variant specifically targets applications requiring a 24 VDC output level.

Replacement Considerations

Compatible replacements include STMicroelectronics L7824CV or similar L7824 variants from other manufacturers. Verify pinout compatibility and thermal resistance values when substituting to ensure proper circuit operation.
