L7815ABP

Overview

The L7815ABP is a three-terminal positive linear voltage regulator from the L78xx series by STMicroelectronics. It provides a fixed 15V output with 2% tolerance and supports up to 1A output current when adequately heat-sunk. The device operates within an extended temperature range, featuring internal thermal overload protection, short-circuit protection, and safe area protection. It utilizes a TO-220FP package for through-hole mounting.

Feature Summary

• Integrated thermal shutdown and current limiting for robust operation
• Fixed 15V output with high precision tolerance
• Extended temperature range capability

Applications

• Local on-card regulation
• Elimination of noise in single-point distribution systems
• General purpose power supply conditioning

Procurement Notes

Verify the specific suffix 'BP' against the manufacturer's official datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure the ordering code matches the required lead-free compliance status and regional certification requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring a stable 15V rail with moderate current demands. Consider the thermal dissipation capabilities of the TO-220FP package relative to the expected load current and ambient temperature conditions to ensure reliable performance without external cooling enhancements.

Part Context

This part belongs to the L78xx family of three-terminal positive regulators. These devices are designed to replace fixed divider networks, offering local regulation to improve system reliability. The L7815ABP specifically targets industrial and commercial environments requiring precise voltage levels.

Replacement Considerations

Compatible substitutes include other L7815 variants from different manufacturers or equivalent parts within the same STMicroelectronics lineup, provided they share identical pinout, voltage rating, and package dimensions.
