Overview
The L7924ACV is a three-terminal negative voltage regulator from the L79xxAC series, manufactured by STMicroelectronics. It provides a fixed output voltage of -24 V with an output current capability up to 1.5 A. The device features thermal overload protection, short circuit protection, and output transition SOA protection. It is designed for local on-card regulation and split power supplies, eliminating distribution problems associated with single-point regulation. The component is housed in a TO-220 package.
Feature Summary
- Provides fixed negative voltage regulation suitable for split power supply configurations
- Includes internal thermal overload protection to prevent damage under excessive heat conditions
- Features built-in short circuit protection to safeguard against output faults
- Offers output transition safe operating area (SOA) protection
Applications
- Local on-card voltage regulation
- Split power supply systems
- Negative voltage generation circuits
Procurement Notes
Verify that the specific part number matches the required -24 V output specification and TO-220 package type. Confirm the manufacturer is STMicroelectronics to ensure compliance with the documented electrical characteristics. Check datasheet revisions for any updates to maximum ratings or application notes before finalizing procurement specifications.
Selection Notes
Select this component when a stable -24 V negative rail is required with currents up to 1.5 A. Ensure adequate heat sinking is provided to support high current delivery, as performance depends on thermal management. Verify input voltage ranges fall within the absolute maximum ratings specified for the -24 V variant to maintain regulatory stability.
Part Context
This component belongs to the L79xxAC series of three-terminal negative regulators. The series includes various fixed output voltages such as -5 V, -8 V, -12 V, and -15 V. These devices share common features like thermal and short circuit protection and are available in TO-220 and D2PAK packages. They are designed to complement the L78xxA positive standard series.
Replacement Considerations
Compatible substitutes within the same family include L7924ACD2T. Other variants in the L79xxAC series offer different fixed output voltages but share similar protective features and package options.
