L7808

The L7808 is a three-terminal positive voltage regulator that provides a stable +8V output from a higher input voltage. It is designed to supply up to 1.5A of current with reliable performance. The L7808 is commonly used in power supply circuits to provide a consistent +8V rail for various electronic and electrical applications.

Key Features:

• Fixed positive output voltage of +8V
• Capable of delivering up to 1.5A of current
• High voltage regulation with low dropout
• Built-in thermal overload and short-circuit protection
• Simple to use with minimal external components
• Compatible with standard 3-terminal voltage regulator applications

Technical Specifications:

• Output Voltage: +8V
• Maximum Output Current: 1.5A
• Input Voltage Range: Up to +35V
• Dropout Voltage: 2V (typical)
• Line Regulation: 0.01% (typical)
• Load Regulation: 0.1% (typical)
• Package Type: TO-220, D2PAK

Applications:

• Positive voltage power supplies
• Voltage regulation in analog and digital circuits
• Power management in electronic devices
• Battery-operated circuits requiring positive voltage

Usage:

1. Connect the input voltage to the input terminal (IN), ensuring it is positive relative to the ground.
2. Connect the output terminal (OUT) to the load or circuit requiring the +8V output.
3. Ensure that the ground terminal (GND) is properly connected to the system ground.
4. Use a suitable heatsink if operating near the maximum current limit to ensure adequate cooling.

Caution:

• Verify input voltage to avoid exceeding the regulator’s maximum rating.
• Ensure proper heat dissipation to prevent overheating.
• Verify polarity to avoid damage to the regulator and connected components.
