Overview
The L7815ABV-DG is a three-terminal positive linear voltage regulator from the STMicroelectronics L78xx series, providing a fixed 15V output. It supports an output current of up to 1.5A and operates within an input voltage range of up to 40V. The device features line regulation of 150mV and load regulation of 100mV, with a typical static current of 6mA. Designed for through-hole installation in a TO-220 package with three pins, it functions reliably across a temperature range of -40°C to 125°C.
Feature Summary
- Integrates internal current limiting, thermal shutdown, and safe area protection for robust operation.
- Provides local on-card regulation to eliminate distribution problems associated with single-point regulation.
- Capable of delivering over 1A output current when adequate heat sinking is provided.
Applications
- Local or on-card voltage regulation
- Split power supply systems requiring ±15V outputs
- General-purpose DC to DC conversion
Procurement Notes
Verify the specific suffix 'DG' against official STMicroelectronics documentation to confirm RoHS compliance status and manufacturing origin details. Ensure the selected package variant matches the required thermal dissipation capabilities for the intended 1.5A load application. Cross-reference the part number with authorized distributors to confirm availability and authenticity.
Selection Notes
Select this component for applications requiring a fixed 15V output with high current capability up to 1.5A. Consider the TO-220 package for its thermal performance advantages over smaller footprints. Evaluate the maximum input voltage limit of 40V to ensure compatibility with the system's power supply rails. Verify that the operating temperature range meets the environmental requirements of the deployment site.
Part Context
This regulator belongs to the L78xx family of three-terminal positive regulators, which are widely used for their reliability and ease of integration. The series offers various fixed output voltages and packages, including TO-220, TO-220FP, D2PAK, and DPAK. These devices are designed to provide stable voltage regulation in diverse electronic circuits, serving as a fundamental building block for power management solutions.
Replacement Considerations
Compatible substitutes include other manufacturers' 7815 variants such as LM341T-15/NOPB. When replacing, verify pinout compatibility and thermal resistance characteristics to maintain system performance and safety margins.
