Instructions for Use:

1. Pin Configuration:

   • Pin 1 (Input): Connect to the unregulated input voltage.
   • Pin 2 (Ground): Connect to the common ground.
   • Pin 3 (Output): Connect to the load or circuit requiring a regulated 5V supply.

2. Input Voltage:

   • Ensure the input voltage is within the range of 7.5V to 35V to avoid damage to the regulator.

3. Output Voltage:

   • The output voltage is fixed at 5V. It can vary slightly due to manufacturing tolerances but will typically be between 4.8V and 5.2V.

4. Heat Dissipation:

   • For high current applications, use a heat sink to manage the thermal resistance. The typical thermal resistance (J-A) is 65掳C/W.
   • Calculate the power dissipation (PD) using the formula: PD = (VI - VO) * IO.

5. Capacitors:

   • Add a 0.33渭F capacitor between the input and ground to filter out noise and improve stability.
   • Optionally, add a 0.1渭F capacitor between the output and ground to further stabilize the output voltage.

6. Mounting:

   • Ensure proper mounting to a heatsink if operating at high currents to prevent overheating.
   • Use insulated mounting hardware to avoid short circuits.

7. Storage and Handling:

   • Store in a dry, cool place away from direct sunlight.
   • Handle with care to avoid damaging the pins or the package.

8. Safety:

   • Always ensure the input voltage is within the specified range to prevent damage to the regulator and connected circuits.
   • Use appropriate fuses or circuit breakers to protect against overcurrent conditions.
