Instructions:

1. Power Supply Connection:

   • Connect the input voltage to the "IN" pin.
   • Connect the output voltage to the "OUT" pin.
   • Ground both the input and output circuits to the "GND" pin.

2. Capacitor Requirements:

   • Place a 10μF tantalum or electrolytic capacitor between the "IN" and "GND" pins as close to the regulator as possible.
   • Place a 10μF tantalum or electrolytic capacitor between the "OUT" and "GND" pins to ensure stability.

3. Heat Dissipation:

   • For high current applications, ensure adequate heat dissipation by using a heatsink or thermal pad.
   • The thermal resistance from junction to ambient (θJA) is 65°C/W for the TO-220 package.

4. PCB Layout:

   • Keep the traces short and wide to minimize voltage drop and inductance.
   • Ensure proper grounding to avoid noise and instability.

5. Storage and Handling:

   • Store in a dry environment to prevent moisture damage.
   • Handle with care to avoid mechanical stress on the leads and package.

6. Testing:

   • Before final assembly, test the regulator with a known load to ensure it meets the specified output voltage and current requirements.
