Instructions for SGM2521:

1. Input Capacitor Selection:

   • Place a ceramic capacitor of at least 1渭F close to the input pins for stability and transient response.

2. Output Capacitor Selection:

   • Use a ceramic capacitor with a value between 1渭F and 10渭F on the output to ensure stability.

3. PCB Layout Recommendations:

   • Keep the distance between the input and output capacitors and the IC as short as possible.
   • Ensure adequate clearance and proper grounding to minimize noise.

4. Operating Temperature Range:

   • The device is designed to operate within the temperature range of -40掳C to +85掳C.

5. Handling Static Electricity:

   • The device is sensitive to electrostatic discharge (ESD). Handle with appropriate ESD precautions.

6. Storage and Packaging:

   • Store in original packaging in a dry, cool place to prevent damage from moisture or physical stress.
