Overview
The L7824CP is a positive linear voltage regulator from the STMicroelectronics L78 series, housed in a TO-220-3 FP package. It provides a fixed output voltage of 24 V with a maximum output current of 1.5 A. The device operates within an input voltage range of 26 V to 40 V and supports junction temperatures up to +125 C. Key electrical parameters include a line regulation of 240 mV, load regulation of 100 mV, and a typical power supply rejection ratio (PSRR) of 50 dB.
Feature Summary
- Provides local on-card regulation to eliminate single-point regulation issues
- Includes internal thermal shutdown and overcurrent limiting for safety
- Features output short-circuit protection and safe operating area (SOA) protection
Applications
- General-purpose electronic equipment requiring stable 24 V DC power
- Industrial control systems utilizing local board-level regulation
- Power supply modules for embedded applications
Procurement Notes
Verify the specific suffix 'CP' corresponds to the TO-220-3 FP through-hole package variant when sourcing. Confirm that the required input voltage headroom meets the minimum 26 V specification to ensure proper regulation under all load conditions. Check datasheet revisions for any updates regarding thermal resistance values or absolute maximum ratings before finalizing component selection.
Selection Notes
Select this component when a fixed 24 V output at up to 1.5 A is required without external feedback networks. Ensure the application environment allows for adequate heat dissipation given the TO-220 package form factor. Consider the 26 V minimum input requirement to maintain dropout voltage margins during operation.
Part Context
This part belongs to the L78xx family of three-terminal positive linear regulators manufactured by STMicroelectronics. The L78 series is widely used for its simplicity and reliability in providing fixed output voltages ranging from 5 V to 24 V. The L7824CP specifically denotes the 24 V output version within this established product line.
FAQ
