Instructions for Use:

  1. Supply Voltage (Vcc):

    • Ensure the supply voltage is within the specified range (4.5V to 5.5V) to avoid damage or improper operation.
  2. Quiescent Current (Iq):

    • The quiescent current is typically 10 μA, but can go up to 15 μA. This is the current consumed by the regulator when no load is present.
  3. Output Voltage (Vo):

    • The regulated output voltage is 3.3V. This is the voltage provided to the load under normal operating conditions.
  4. Load Regulation:

    • The change in output voltage with respect to load current should not exceed 0.1%. This ensures stable output voltage even as the load changes.
  5. Line Regulation:

    • The change in output voltage with respect to input voltage should not exceed 0.05%. This ensures the output remains stable even if the input voltage fluctuates.
  6. Dropout Voltage (Vdo):

    • The dropout voltage is typically 0.3V. Ensure that the input voltage is at least 0.3V higher than the output voltage to maintain regulation.
  7. Thermal Shutdown Temperature (Tsd):

    • The device will shut down if the temperature exceeds 150°C to prevent damage from overheating.
  8. Short-Circuit Current (Isc):

    • The maximum current during a short circuit is 200mA. The device has internal protection to limit current and prevent damage.
  9. Operating Temperature Range (Topr):

    • The device is designed to operate within an ambient temperature range of -40°C to 85°C.
  10. Storage Temperature Range (Tstg):

    • The device can be stored at temperatures ranging from -65°C to 150°C without damage.

Additional Notes:

  • Always ensure proper heat dissipation if the device is expected to operate near its maximum power dissipation.
  • Use appropriate decoupling capacitors on the input and output to filter noise and stabilize the output voltage.
  • Refer to the datasheet for detailed pin configurations and application circuits.
