Overview
The STMicroelectronics L7824ABD2T is a three-terminal positive linear voltage regulator from the L7800A series, housed in a D2PAK surface-mount package. It provides a fixed 24V output with a maximum current capability exceeding 1A. The device features internal thermal overload protection, short-circuit current limiting, and safe operating area (SOA) protection. It operates within an input voltage range of up to 40V and supports junction temperatures up to 150°C.
Feature Summary
- Fixed 24V output voltage with high precision tolerance
- Internal thermal shutdown and current limiting for robustness
- Safe Operating Area (SOA) protection prevents destruction under fault conditions
- Surface-mount D2PAK packaging for efficient board integration
Applications
- Local on-card regulation in electronic circuits
- Power supplies requiring stable 24V DC rails
- Industrial equipment power management systems
Procurement Notes
Verify the specific suffix 'BD2T' corresponds to the D2PAK-3 package and RoHS compliance status as per the official datasheet. Confirm that the 'A' grade designation meets the required 2% voltage tolerance specifications for the application. Ensure heat sinking requirements are calculated based on the expected load current and ambient temperature to maintain safe junction temperatures.
Selection Notes
Select this component when a fixed 24V output is required with higher precision than standard L78xx devices. The D2PAK package is suitable for automated surface-mount assembly processes. Consider the thermal dissipation capabilities of the PCB layout, as the device delivers over 1A and requires adequate heat sinking to handle power loss effectively during operation.
Part Context
This part belongs to the L7800A series of precision regulators, which offers tighter voltage tolerances compared to the standard L78xx family. The series is designed for applications demanding reliable local regulation, eliminating distribution issues associated with single-point regulation systems. It is widely used in industrial and commercial electronics where stable voltage delivery is critical.
Replacement Considerations
Compatible substitutes include other L7824 variants such as L7824ACD2T or L7824CD2T, provided the package type and electrical characteristics align with the design requirements. Verify pinout compatibility and thermal performance metrics before substitution.
