Overview
The L7824ABD2T-TR is a fixed positive linear voltage regulator from the STMicroelectronics L78 series, housed in a D2PAK surface-mount package. It provides a fixed output voltage of 24 V with a maximum output current of 1.5 A. The device supports an input voltage range from 26 V to 40 V and operates within a temperature range of -40 °C to +125 °C. Internal protections include thermal shutdown and safe area protection.
Feature Summary
- Integrated thermal overload protection prevents damage during excessive power dissipation.
- Internal current limiting and safe area protection safeguard against short circuits and overloads.
- Fixed output voltage eliminates the need for external feedback components.
Applications
- General-purpose power supply regulation
- Local on-card regulation for distributed power systems
- Positive regulated power supplies
Procurement Notes
Verify the specific suffix 'AB' against official datasheets to confirm the extended temperature range (-40°C to +125°C) and electrical characteristics, as standard variants may differ. Ensure the D2PAK footprint matches the PCB design. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement.
Selection Notes
Select this component when a stable 24 V output at up to 1.5 A is required in a surface-mount form factor. The D2PAK package offers improved thermal performance compared to smaller SMD packages. Verify that the input voltage remains within the specified 26 V to 40 V range to ensure proper regulation and avoid dropout or overvoltage conditions.
Part Context
This part belongs to the L78xx family of three-terminal positive linear regulators. These devices are widely used for their simplicity and reliability in basic voltage regulation tasks. The L7824 variant specifically targets applications requiring a 24 V rail, while the ABD2T suffix indicates the surface-mount D2PAK packaging and specific manufacturing lot codes.
Replacement Considerations
Compatible substitutes include other L7824 variants in different packages (e.g., TO-220) or equivalent 24 V/1.5 A linear regulators from other manufacturers, provided pinouts and thermal requirements match.
