L7824CD2T-TR

Overview

The L7824CD2T-TR is a fixed-output positive linear voltage regulator from the STMicroelectronics L78 series. It provides a nominal output voltage of 24 V with a maximum output current capability of 1.5 A. The device operates within an input voltage range of 26 V to 40 V and supports surface-mount installation in a D2PAK package. Internal protection mechanisms include thermal shutdown and current limiting, ensuring safe operation under overload conditions.

Feature Summary

• Fixed 24 V output for stable power supply applications
• Integrated thermal shutdown and short-circuit protection
• Surface-mount D2PAK packaging for automated assembly

Applications

• Local on-card voltage regulation
• Positive power supply lines
• General-purpose linear regulation circuits

Procurement Notes

Verify the specific suffix 'D2T' confirms the D2PAK surface-mount package variant rather than through-hole alternatives like TO-220FP. Confirm RoHS compliance status via the manufacturer datasheet before integration. Ensure input voltage remains above 26 V to maintain regulation. Validate thermal management requirements for the D2PAK footprint based on expected load currents.

Selection Notes

Select this component when a fixed 24 V output is required with up to 1.5 A capacity in a surface-mount form factor. Compare against the L7824CP if through-hole mounting is preferred. Consider the L78M24CDT-TR if lower current (0.5 A) and smaller TO-252 packaging are sufficient for the design constraints.

Part Context

This part belongs to the L78xx family of three-terminal positive linear regulators. These devices are designed to eliminate the complexity of single-point regulation by providing local card-level control. The L78 series is widely used in industrial and consumer electronics for reliable voltage stabilization.

Replacement Considerations

L7824CP: Through-hole equivalent in TO-220FP package. L78M24CDT-TR: Lower current (0.5 A) version in TO-252 package.
