Instructions for Use:

  1. Input Connection:

    • Connect the input voltage (VIN) to the power supply.
    • Ensure the input voltage is within the specified range (4.5V to 28V).
  2. Output Configuration:

    • Adjust the output voltage (VOUT) using the external resistor divider network.
    • The output voltage can be set between 0.8V and 18V.
  3. Output Load:

    • The maximum continuous output current (IOUT) is 3A.
    • Ensure the load does not exceed this limit to avoid damage.
  4. Efficiency:

    • The efficiency is typically 92% at full load when converting from 12V to 5V.
    • Monitor the temperature and efficiency under different load conditions.
  5. Quiescent Current:

    • The quiescent current (IQ) is approximately 25μA with no load.
    • This low quiescent current helps in reducing power consumption in low-power applications.
  6. Regulation:

    • Line regulation (ΔVOUT/ΔVIN) is typically 0.01% per volt.
    • Load regulation (ΔVOUT/ΔIOUT) is typically 0.05% per ampere.
    • These parameters ensure stable output voltage under varying input and load conditions.
  7. Dropout Voltage:

    • The dropout voltage (VDROPOUT) is typically 1.2V at full load.
    • Ensure the input voltage is sufficiently higher than the output voltage to maintain regulation.
  8. PSRR (Power Supply Rejection Ratio):

    • The PSRR is typically 60dB at 1kHz.
    • This helps in filtering out noise from the input power supply.
  9. Temperature Considerations:

    • The operating temperature range (TOPR) is -40°C to 125°C.
    • The storage temperature range (TSTG) is -65°C to 150°C.
    • Ensure the device operates within these temperature limits to avoid thermal stress.
  10. Package Type:

    • The DP8473V is available in a SOT-23 package.
    • Follow standard PCB layout guidelines for SOT-23 packages to ensure reliable operation.
