Instructions for Use:

  1. Supply Voltage (VIN):

    • Ensure the input voltage is within the specified range of 2.7V to 5.5V.
    • Connect the input voltage to the VIN pin.
  2. Output Voltage (VOUT):

    • The output voltage is fixed at 3.3V. No external components are required for voltage regulation.
    • Connect the load to the VOUT pin.
  3. Output Current (IOUT):

    • The device can provide up to 800mA of continuous output current.
    • Ensure the load does not exceed this limit to avoid overheating or damage.
  4. Quiescent Current (IQ):

    • The quiescent current is typically 1.5mA when there is no load.
    • This should be considered in low-power applications.
  5. Dropout Voltage (VDROPOUT):

    • The dropout voltage is typically 0.3V at maximum load.
    • Ensure the input voltage is at least 0.3V higher than the output voltage to maintain regulation.
  6. Load Regulation:

    • The change in output voltage due to load variations is typically 0.5%.
    • This ensures stable output under varying load conditions.
  7. Line Regulation:

    • The change in output voltage due to input voltage variations is typically 0.2%.
    • This ensures stable output even with fluctuations in the input voltage.
  8. Thermal Shutdown (TSD):

    • The device will shut down if the junction temperature exceeds 160°C.
    • Ensure adequate heat dissipation to prevent thermal shutdown.
  9. Operating Temperature (TOPR):

    • The device operates reliably within the temperature range of -40°C to 85°C.
    • Avoid operating outside this range to prevent performance degradation or failure.
  10. Storage Temperature (TSTG):

    • The device can be stored within the temperature range of -65°C to 150°C.
    • Ensure proper storage conditions to maintain device integrity.
