Overview
The L7824ABV-DG is a three-terminal positive linear voltage regulator from the STMicroelectronics L78 series. It provides a fixed output voltage of 24 V with a maximum output current of 1.5 A. The device features thermal overload protection, short circuit protection, and output safe operating area (SOA) protection. It operates within a junction temperature range of -40 °C to +125 °C and has a typical quiescent current of 4.6 mA. The component is housed in a TO-220AB package for through-hole mounting.
Feature Summary
- Provides local on-card regulation to eliminate single-point regulation issues
- Includes internal thermal shutdown and current limiting for safety
- Offers fixed output voltage options ranging from 5 V to 24 V
Applications
- General-purpose power supply units requiring stable 24 V output
- Battery chargers utilizing linear regulation topology
- Industrial control systems needing reliable voltage stabilization
Procurement Notes
Verify the specific suffix 'DG' against the manufacturer's official datasheet to confirm RoHS compliance status and exact pinout configuration. Ensure the ordering part number matches the required package type and environmental specifications before procurement. Cross-reference the manufacturer's latest documentation to validate availability and any potential obsolescence notices.
Selection Notes
Select this component when a fixed 24 V output is required with up to 1.5 A load capacity. Consider the thermal management requirements due to linear regulation efficiency losses. Verify that the input voltage remains within the specified limits to ensure proper dropout voltage operation and prevent overheating under maximum load conditions.
Part Context
This component belongs to the L78 series of fixed-output positive linear regulators. The series is widely used for eliminating problems associated with single-point regulation by providing local on-card regulation. These devices are designed for applications requiring simple, robust voltage regulation with built-in safety features.
Replacement Considerations
Compatible substitutes include other L78 series variants such as L7824CV or L7824CP, provided they meet the same electrical specifications and package requirements. Verify pin compatibility and thermal performance characteristics before substitution.
