Description
📦 Description:
The ST L7809CV is a three-terminal positive linear voltage regulator IC in a TO-220 package, delivering a fixed 9V output with up to 1.5A current capacity. It features internal current limiting, thermal shutdown, and safe operating area protection, making it robust and reliable for both DIY and industrial use.
This IC is ideal for regulating higher voltage sources like 12V or 15V down to a stable 9V level in electronic circuits.
🧊 Note:
For optimal thermal performance, it is recommended to use a compatible TO-220 heat sink with thermal paste or pad (sold separately).
Product colour may vary slightly depending on batch and availability. Functionality remains the same. (Refer to product image for illustration. Check datasheet for specifications.)
