Overview
The L7915CP is a three-terminal negative voltage regulator from the L79xxC series, manufactured by STMicroelectronics. It provides a fixed output voltage of -15 V with a maximum output current capability of 1.5 A. The device supports a DC input voltage range up to -35 V and operates within a junction temperature range of 0 °C to 150 °C. It utilizes a TO-220FP through-hole package.
Feature Summary
- Integrated thermal overload protection safeguards against excessive heat generation.
- Built-in short circuit protection limits damage during fault conditions.
- Output transition SOA protection ensures safe operation under varying load dynamics.
Applications
- Local on-card regulation for distributed power systems
- Split power supply configurations requiring negative rails
- General-purpose linear voltage regulation
Procurement Notes
Verify that the specific order code matches the required package type and environmental compliance grade. Confirm the revision level aligns with design specifications. Ensure adequate thermal management solutions are integrated into the PCB layout to maintain junction temperatures within the specified operational limits during high-current loads.
Selection Notes
Select this component when a stable negative voltage rail is required for analog or digital circuits. Consider the thermal resistance characteristics of the TO-220FP package relative to the expected power dissipation. Evaluate the dropout voltage requirements to ensure sufficient input-to-output differential is maintained across the full operating load range.
Part Context
This part belongs to the L79xxC family of standard negative regulators. It shares pinout compatibility and functional architecture with other members of the series, such as the L7905C and L7912C, allowing for modular design approaches in multi-voltage power supply systems.
Replacement Considerations
Cross-reference with other manufacturers' -15V negative regulators offering similar current ratings and package footprints. Verify electrical parameter equivalence and mechanical dimensions before substitution.
