STMicroelectronics Voltage Regulators - Linear L78S09CV-DG

The L78S09CV-DG is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a fixed output voltage of 9 V with a maximum output current of 2 A. It comes in a TO-220 package, making it suitable for various applications requiring local on-card regulation. The device features internal current limiting, thermal shutdown, and safe area protection, enhancing its reliability and durability. It can be used in conjunction with external components to achieve adjustable voltages and currents, although it is primarily intended for fixed voltage regulation. This regulator is ideal for projects that require stable voltage supply with robust protection features.
