About L7805CV
The L7805CV is a voltage regulator integrated circuit (IC) that is commonly used to provide a stable and fixed output voltage of +5 volts. This component is part of the 78xx series of voltage regulators, where "78" denotes a positive voltage regulator and "05" indicates the fixed output voltage of +5 volts.

Here are some key points about the L7805CV:
1. Voltage Regulation: The primary function of the L7805CV is to regulate the input voltage and maintain a constant output voltage of +5V.
2. Input Voltage Range: The typical input voltage range for the L7805CV is around 7V to 35V. It can handle higher input voltages, but the excess voltage is "dropped" or dissipated as heat.
3. Output Current: The maximum output current is around 1.5 amps. It can supply a stable +5V output for electronic circuits within this current limit.
4. Three-Terminal Device: The L7805CV has three terminals: Input (Vin), Ground (GND), and Output (Vout). Proper connection and orientation of these terminals are crucial for correct operation.
5. Heat Dissipation: The L7805CV may generate some heat, especially when the input voltage is significantly higher than the output voltage. To prevent overheating, it's common to use a heatsink or ensure adequate ventilation.
