    Products Detail

    L9911U Overview


    A total of 1outputs are supported by this voltage regulator. The rectifier regulator is packaged in Multiwatt-8 (Straight Leads) to facilitate transportation. We are ready to ship in Tube packages. For easy adaptability, there is a universal mount Through Hole. There are a number of applications targeted at Power Supply, Automotive Applications. As a precaution, it is recommended to set the operating temperature to -40°C~150°C to prevent malfunctions. This external regulator requires a voltage input of 7V~18V. There are 8terminals on the voltage regulator. As a BRUSH DC MOTOR CONTROLLER regulator, the electronic part has received high praise. Pinouts for the rectifier regulator begin at 8. If you are looking for pin-to-pin solutions for a specific application, please search L9911. There is a Through Hole on the board for mounting to a PCB or other board. 8pins are present on the power regulators. The voltage controller plays an important role in the industry, as do other Automotive Circuits. Currently, the electrical regulator should output 15A. There must be an input voltage higher than 7Vin order to operate this rectifier regulator. As the power regulator is supplied with a voltage of 12.5V, it can perform a wide range of demanding tasks.
