Instructions for Use:

1. Circuit Configuration:

   • Connect the input voltage to the "Input" pin.
   • Connect the output voltage to the "Output" pin.
   • Ground the "Common" pin.

2. Capacitors:

   • Place a 0.33μF capacitor between the input and ground close to the regulator.
   • Optionally, place a 0.1μF capacitor between the output and ground to improve transient response.

3. Heat Dissipation:

   • Ensure adequate heat sinking if operating near maximum load conditions to maintain junction temperature within specified limits.

4. Input Filtering:

   • For noisy environments, consider adding additional filtering on the input side.

5. Mounting:

   • Mount in a way that facilitates cooling and ensures mechanical stability.

6. Power-On Sequence:

   • Apply input voltage gradually to avoid inrush currents.

7. Storage:

   • Store in a dry environment away from corrosive substances.
