Instructions for BD809

  1. Power Supply Connection:

    • Connect the input voltage (VIN) to the power supply.
    • Ensure the input voltage is within the specified range (2.7V to 5.5V).
  2. Output Configuration:

    • Set the output voltage (VOUT) by using external resistors or selecting a fixed output voltage version if available.
    • The output voltage should be within the range of 1.8V to 3.3V.
  3. Load Connection:

    • Connect the load to the output terminal (VOUT).
    • Ensure the load current does not exceed the maximum output current (500mA).
  4. Capacitors:

    • Use a 1渭F ceramic capacitor on the input side (VIN) to filter out noise and stabilize the input voltage.
    • Use a 1渭F ceramic capacitor on the output side (VOUT) to ensure stable operation and minimize ripple.
  5. Thermal Considerations:

    • Ensure adequate heat dissipation, especially when operating at high currents or in high ambient temperatures.
    • The operating temperature range is -40掳C to 85掳C.
  6. Shutdown Function:

    • To disable the regulator, apply a low signal to the shutdown pin (SD).
    • The shutdown current is very low, typically around 0.1渭A.
  7. Storage:

    • Store the device in a dry environment with temperatures between -65掳C and 150掳C.
  8. Handling Precautions:

    • Handle the device with care to avoid damage from electrostatic discharge (ESD).
    • Follow standard ESD protection guidelines during assembly and handling.
  9. Testing:

    • Before finalizing the design, test the regulator under various conditions to ensure it meets the required specifications and performance criteria.
