About this product
The L7908CV is a three-terminal fixed negative voltage regulator with a -8 V output and up to 1 A output current when adequately heat-sunk. It is available in TO-220, TO-220FP and D2PAK packages. It includes thermal overload, short-circuit and safe operating area protection and is commonly used for the negative rail in split supplies.

Frequently asked questions
How should the L7908CV be wired?
It has three terminals: unregulated negative input, common ground, and regulated -8 V output. Confirm the pin order for your package in the datasheet, and keep the input more negative than -8 V by the regulator's required margin.
Can the L7908CV be used in split power supplies?
Yes. Its negative fixed output is suited to the negative rail of split supplies, and it pairs with the L78xx positive series of the same voltage option. Confirm the grounding and input arrangement in the datasheet.
