Overview
The L7824CV is a positive linear voltage regulator from the STMicroelectronics L78xx series, providing a fixed 24 V output with a maximum current of 1.5 A. It operates within an input voltage range of 26 V to 40 V and features internal protections including thermal overload shutdown, short-circuit limiting, and safe operating area (SOA) protection. The device utilizes a TO-220-3 through-hole package, suitable for local card regulation to eliminate distribution issues associated with single-point regulation.
Feature Summary
- Provides fixed 24 V output with up to 1.5 A current capability
- Includes internal thermal overload shutdown and short-circuit protection
- Features safe operating area (SOA) protection for stability
- Designed for local on-card regulation applications
Applications
- Power supply management systems
- Local on-card voltage regulation
- General-purpose electronic circuits requiring stable 24 V DC
Procurement Notes
Verify the specific suffix 'CV' against the manufacturer's official datasheet to confirm pinout compatibility and exact electrical tolerances. Ensure the procurement channel provides authentic STMicroelectronics components to avoid counterfeit risks. Confirm that the TO-220-3 package matches the target PCB footprint and thermal requirements before finalizing orders.
Selection Notes
Select this component when a fixed 24 V output at 1.5 A is required in a through-hole configuration. It is appropriate for designs needing robust internal protection against thermal and short-circuit events. Consider the TO-220-3 package size and thermal dissipation capabilities relative to the application's power budget and ambient temperature constraints.
Part Context
The L7824CV belongs to the widely used L78xx family of three-terminal positive linear regulators. This series is known for its simplicity and reliability in standard voltage regulation tasks. The '24' designation indicates the fixed 24 V output voltage, while 'CV' typically denotes the specific package and temperature grade variant offered by STMicroelectronics.
Replacement Considerations
Compatible substitutes include other L7824 variants such as L7824ACV or L7824CDT, provided they meet the same 24 V/1.5 A specifications and package requirements. Verify pinout compatibility and thermal performance characteristics before substituting.
