L7809CV

Overview

The L7809CV is a fixed positive linear voltage regulator from the STMicroelectronics L78xx series. It provides a nominal output voltage of 9V with a maximum continuous output current of 1.5A. The device accepts an input voltage range up to 35V and operates within a junction temperature range of 0°C to 125°C. Internal circuitry includes overcurrent protection, thermal shutdown, and safe area protection.

Feature Summary

Fixed 9V output voltage
Internal overcurrent and thermal protection
TO-220 through-hole package

Applications

General-purpose power supplies
Embedded systems biasing
Industrial control circuits

Procurement Notes

Verify the manufacturer part number against official STMicroelectronics documentation to confirm specifications. Ensure the component matches the required TO-220-3 package and electrical ratings for your specific design application.

Selection Notes

Select this component when a stable 9V supply is needed at currents up to 1.5A. Consider the thermal dissipation requirements associated with the voltage drop across the regulator in your system design.

Part Context

This component belongs to the L78xx family of three-terminal linear regulators. These devices are widely used for basic voltage regulation tasks requiring moderate current capabilities and simple implementation.

Replacement Considerations

Equivalent parts include MC7809CTG from onsemi or LM7809 from Texas Instruments, provided they meet the same electrical and mechanical specifications.
