Instructions

1. Mounting:

   • Ensure the component is mounted on a heat sink if operating at high output currents to maintain temperature within the operating range.
   • Align the component with the PCB according to the pin configuration.

2. Input Connection:

   • Connect the input voltage to Pin 1 (IN).
   • Ensure the input voltage is within the specified range (4.5V to 28V).

3. Ground Connection:

   • Connect the ground to Pin 2 (GND).
   • Ensure a solid ground connection to avoid instability and noise.

4. Output Connection:

   • Connect the load to Pin 3 (OUT).
   • The output voltage will be regulated to 5V.

5. Capacitors:

   • Place a 10渭F electrolytic capacitor between IN and GND close to the component to filter input noise.
   • Place a 10渭F electrolytic capacitor between OUT and GND to stabilize the output voltage.

6. Testing:

   • After assembly, apply the input voltage and measure the output voltage to ensure it is stable at 5V.
   • Check the temperature of the component to ensure it is within the operating range.

7. Storage:

   • Store the component in a dry environment within the specified storage temperature range (-65掳C to 150掳C).

8. Handling:

   • Handle the component with care to avoid damage to the pins and body.
   • Use proper ESD protection to prevent electrostatic discharge damage.
