L7824CD2T

Overview

The L7824CD2T is a fixed-output positive linear voltage regulator from the STMicroelectronics L78 series. It provides a nominal 24 V output with a maximum continuous current of 1.5 A. The device operates within an input voltage range of 26 V to 40 V and features a D2PAK surface-mount package. Electrical characteristics include a line regulation of 240 mV, load regulation of 100 mV, and a typical power supply rejection ratio (PSRR) of 50 dB. Internal protections encompass thermal overload shutdown, short-circuit protection, and safe operating area (SOA) limits.

Feature Summary

• Fixed 24 V output for local on-card regulation
• Integrated thermal overload and short-circuit protection
• Safe Operating Area (SOA) protection for robust operation

Applications

• Local voltage regulation in electronic equipment
• Power supplies requiring stable 24 V DC rails
• Industrial control systems with distributed power architectures

Procurement Notes

Verify the specific suffix 'D2T' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration and pinout orientation. Ensure that the ordering information matches the required surface-mount package type and that all electrical parameters align with the design specifications before procurement.

Selection Notes

Select this component when a fixed 24 V output is required with up to 1.5 A capacity in a surface-mount format. Consider the thermal dissipation requirements associated with the D2PAK package under high input-to-output voltage differentials. Verify that the application environment remains within the specified operating temperature range and that adequate heat sinking is provided for sustained high-current loads.

Part Context

This part belongs to the L78xx family of three-terminal positive regulators designed for wide-ranging applications. These devices eliminate distribution problems by providing local regulation. The L78 series is characterized by internal current limiting and thermal shutdown, making them highly reliable for general-purpose voltage regulation tasks in commercial and industrial electronics.

Replacement Considerations

Compatible replacements include other manufacturers' equivalents offering a fixed 24 V output in a D2PAK-3 package, such as the MC7824CD2T or LM7824 variants. Ensure that any substitute maintains identical pin configurations, thermal performance characteristics, and electrical tolerances to guarantee seamless integration without circuit modification.
