Overview
The L7808CV is a fixed positive linear voltage regulator from the STMicroelectronics L78xx series, housed in a TO-220-3 package. It provides a nominal output voltage of 8 V with a maximum continuous output current of 1.5 A. The device accepts an input voltage range between 14 V and 35 V. Internal protection mechanisms include thermal shutdown and safe area protection against short circuits. The component operates within a temperature range of 0°C to 125°C.
Feature Summary
- Integrated thermal overload protection prevents damage during excessive heat generation.
- Internal circuitry limits current flow to protect against output short circuits.
- Fixed output voltage eliminates the need for external feedback components.
Applications
- General-purpose power supply regulation
- Local on-card regulation for distributed power systems
- Positive regulated power supplies
Procurement Notes
Verify the specific manufacturer lot code and date code upon receipt to ensure authenticity. Confirm that the physical marking matches the L7808CV designation exactly. Check for any obsolescence notices or product change notifications (PCN) issued by STMicroelectronics regarding this specific part number before finalizing procurement plans.
Selection Notes
Select this component when a stable 8 V rail is required at currents up to 1.5 A. Ensure the input voltage remains above 14 V to maintain proper regulation. Verify that the application environment stays within the specified operating temperature range. Consider the thermal dissipation requirements associated with the TO-220 package for the expected load conditions.
Part Context
This device belongs to the L78xx family of three-terminal positive regulators. These components are widely used for basic voltage regulation tasks due to their simplicity and robust internal protections. The L7808CV specifically targets applications requiring an 8 V output level.
Replacement Considerations
Compatible substitutes include the L7808ABV, which offers tighter tolerance specifications, and other industry-standard equivalents such as the LM7808 or MC7808CPT, provided pinouts and electrical ratings align with the design requirements.
