Description
📦 Description:
The ST L7912CV is a 3-terminal negative voltage regulator providing a fixed –12V output with a current capacity of up to 1.5A. Designed for use in dual-supply systems, it complements the positive 78xx series and is used where negative rail regulation is required, such as op-amp power supplies or analog audio designs.
Encased in a TO-220 package, this IC includes internal current limiting, thermal shutdown, and safe operating area protection, ensuring stable and safe performance even under overload conditions.
🧊 Note:
For better heat dissipation, use a TO-220 compatible heatsink (recommended size: 25x15x10mm or similar) along with thermal paste or thermal pad.
Product color may vary slightly depending on batch and availability. (Product image is for illustration; always refer to the official datasheet for accurate specifications.)
