L7808ACV

Overview

The L7808ACV is a fixed positive linear voltage regulator from the STMicroelectronics L78xx series, housed in a TO-220 package. It provides a nominal output voltage of 8 V with a maximum output current capability of 1.5 A. The device supports an input voltage range up to 35 V and operates within a temperature range of 0°C to 125°C. Internal protection features include thermal overload shutdown and safe area compensation.

Feature Summary

• Fixed 8 V output voltage regulation
• Integrated thermal overload protection
• Safe area compensation for load stability

Applications

• General-purpose power supply regulation
• Local on-card regulation for digital logic circuits
• Embedded system power distribution

Procurement Notes

Verify the specific suffix 'ACV' against official datasheets to confirm accuracy class and package type. Ensure the component matches the required 8 V output specification and TO-220 physical dimensions before integration into the design.

Selection Notes

Select this component when a stable 8 V rail is required for low-to-medium current loads. Verify that the input voltage remains within the 35 V limit and that adequate heat sinking is provided to manage power dissipation at higher currents.

Part Context

This part belongs to the L78xx family of three-terminal positive linear regulators. These components are widely used for basic voltage regulation tasks due to their simplicity and robust internal protection mechanisms, serving as standard solutions for converting unregulated DC sources to fixed voltages.
