Description
This regulator comes in various packages, including TO-220, which is popular due to its ease of mounting and good thermal characteristics. It requires only two external capacitors to function properly: one at the input and one at the output, for stability and noise reduction.
The L7808CV is suitable for a wide range of applications, including power supplies for microcontrollers, sensors, and other low-power devices. Its operational temperature range and robustness make it ideal for both consumer electronics and industrial applications. Overall, the L7808CV offers a cost-effective and straightforward solution for voltage regulation in many electronic projects.
Features
1. Output Voltage: Delivers a fixed output of 8V, making it suitable for a range of applications needing a stable voltage supply.
2. Output Current: Can deliver up to 1.5A of continuous current, making it ideal for medium-power applications.
3. Thermal Protection: Includes internal thermal shutdown to prevent damage from overheating, enhancing reliability.
4. Current Limitation: Features internal current limiting to safeguard against overloads.
5. Short-Circuit Protection: Offers protection against short circuits, ensuring safety and durability.
6. Dropout Voltage: Provides a relatively low dropout voltage, which is beneficial for efficient operation in a variety of scenarios.
7. Package Type: Available in a TO-220 package, which aids in heat dissipation and is easy to mount on a heat sink.
8. Versatility: Suitable for use in power supplies, battery chargers, and various electronic circuits requiring a stable voltage.
These features make the L7808CV a robust choice for maintaining a consistent DC power supply in electronic devices.
Package
Pinout
The L7808CV comes in a TO-220 package and typically has three pins:
1. Input (Pin 1): This pin is where the unregulated input voltage is connected. The input voltage must be higher than the desired output voltage (at least 10.5 volts for proper operation).
2. Ground (Pin 2): This pin is connected to the ground of the circuit and is common to both the input and output.
3. Output (Pin 3): This pin provides the regulated output voltage of 8 volts.
The L7808CV is designed to deliver up to 1.5A of output current, provided it is adequately heat-sinked. It includes features such as thermal overload protection and short-circuit protection, making it robust for various applications.
