Instructions for Use:

1. Power Supply Connection: Connect the input voltage (VDD) between 2.7V and 5.5V to the VIN pin. Ensure a stable power supply to avoid fluctuations.
2. Output Configuration: The SI3402-B-GM can provide up to 30mA continuous output current. Connect the load directly to the VOUT pin.
3. Capacitor Requirements: Place a 1μF capacitor close to the VIN pin and a 1μF capacitor close to the VOUT pin for stability.
4. Heat Dissipation: Although the device is designed for low heat generation, ensure adequate ventilation or heat sinking if used in high ambient temperatures.
5. Operating Temperature: The device operates reliably within a temperature range of -40°C to +85°C. Avoid exceeding these limits to prevent damage.
6. PCB Layout: Follow standard PCB layout practices to minimize noise and interference. Keep traces short and direct, especially for power and ground connections.
7. Storage Conditions: Store in a dry, cool place away from direct sunlight and corrosive substances.

For detailed specifications and application notes, refer to the manufacturer’s datasheet.
