L7808CV-DG

Overview

The L7808CV-DG is a fixed positive linear voltage regulator from the STMicroelectronics L78xx series, housed in a TO-220-3 package. It provides a fixed output voltage of 8 V with a maximum output current of 1.5 A. The device accepts an input voltage range from 14 V to 35 V and features internal protections against overload conditions, including thermal shutdown and short-circuit limiting. It operates within a junction temperature range of 0°C to +125°C.

Feature Summary

• Fixed positive output voltage regulation
• Internal thermal overload protection
• Internal short-circuit current limiting

Applications

• General-purpose power supply regulation
• Local on-card regulation for distributed power systems
• Regulation for equipment requiring stable 8V DC rails

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated by the DG suffix. Check for End-of-Life (EOL) notices, as availability may be limited. Ensure proper handling procedures are followed during installation to maintain device integrity.

Selection Notes

Select this component when a fixed 8V output at up to 1.5A is required. Consider the TO-220-3 package for through-hole mounting and adequate heat dissipation. Evaluate input voltage stability to ensure it remains within the 14V to 35V operational window. Verify that thermal management strategies meet the 125°C maximum junction temperature requirement.

Part Context

Part of the widely adopted L78xx family of three-terminal linear regulators. Designed for robust performance in industrial and consumer electronics. Offers a simple solution for voltage step-down applications without complex external circuitry requirements.

Replacement Considerations
