Short Circuit Current	2.4A	Maximum current before short-circuit protection activates.
Operating Temperature	-40°C to 125°C	Temperature range within which the device can operate safely.
Package Type	TO-220, TO-92	Common package types available for this regulator.

Instructions:

1. Connect the Components:

   • Connect the input voltage to the "Input" pin.
   • Connect the output voltage to the "Output" pin.
   • Ensure a capacitor is placed close to the input and output pins for stability (typically 0.33μF on input and 0.1μF on output).

2. Input Voltage Requirements:

   • Ensure the input voltage is at least 2V higher than the output voltage (5V in this case) to maintain regulation.

3. Heat Dissipation:

   • For applications where the input voltage is significantly higher than the output voltage or when high currents are drawn, use a heat sink to dissipate excess heat.

4. Short Circuit Protection:

   • The L7805CV includes internal short-circuit current limiting and thermal overload protection to safeguard against damage.

5. Temperature Considerations:

   • Operate within the specified temperature range to ensure reliable performance and longevity of the regulator.

6. Mounting Orientation:

   • If using a TO-220 package, mount in an upright position for better heat dissipation if not using a heatsink.
