L7824ACV-DG

Overview

The L7824ACV-DG 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 A. The device accepts an input voltage range between 26 V and 40 V. Key electrical parameters include a line regulation of 240 mV, load regulation of 100 mV, and a typical power supply rejection ratio (PSRR) of 54 dB at 120 Hz. The quiescent current is specified at 4.6 mA. It operates within a temperature range of 0°C to +125°C and utilizes a TO-220 package.

Feature Summary

• Integrated thermal overload protection and short-circuit current limiting for operational safety
• Internal safe operating area (SOA) protection prevents device failure under extreme conditions
• Fixed 24 V output eliminates the need for external feedback components

Applications

• Local on-board card voltage regulation
• General-purpose power supplies requiring stable 24 V rails
• Embedded systems with positive polarity requirements

Procurement Notes

Verify the specific suffix 'DG' against the official STMicroelectronics datasheet to confirm pinout compatibility and exact electrical tolerances. Ensure the procurement source provides the original manufacturer's documentation rather than third-party summaries. Cross-reference the ordering code with the latest product change notices to validate manufacturing status and compliance certifications.

Selection Notes

Select this component when a robust, high-current linear regulator is required for 24 V applications. The 1 A output capability exceeds that of the L78Lxx series, making it suitable for moderate power loads. Consider the TO-220 package for through-hole mounting and adequate heat dissipation without additional active cooling solutions in standard ambient environments.

Part Context

This part belongs to the industry-standard L78xx family of three-terminal positive regulators. These devices are widely used for eliminating noise associated with single-point regulation by providing local filtering and stabilization. The L7824 variant specifically targets 24 V distribution networks common in industrial control and telecommunications equipment.

Replacement Considerations

Compatible substitutes include the L7824CV and L7824CP. Verify that alternative packages such as TO-220FP maintain identical pin configurations and thermal performance characteristics before implementation.
