The L7908 is a fixed negative-output linear regulator providing -8V at up to 1.5A. Housed in a TO-220 package, it features a dropout voltage of 1.5V at 1A and a quiescent current of 5mA. This regulator is designed for applications requiring a reliable negative voltage rail.
- High Current: 1.5A output supports demanding analog loads.
- Fixed -8V Output: Simplifies design for negative rail applications.
- TO-220 Package: Excellent thermal performance for continuous operation.
- Low Quiescent Current: 5mA reduces power consumption.
