Instructions for Use:

  1. Supply Voltage (Vcc):

    • Ensure the supply voltage is within the range of 2.7 V to 5.5 V.
    • The typical operating voltage is 5.0 V.
  2. Output Current (Iout):

    • The device can provide up to 150 mA of continuous output current.
    • Do not exceed the maximum output current to avoid damage.
  3. Dropout Voltage (Vdo):

    • The dropout voltage is typically 0.3 V at an output current of 150 mA and a supply voltage of 5.0 V.
    • Ensure that the input voltage is at least 0.3 V higher than the desired output voltage.
  4. Quiescent Current (Iq):

    • The quiescent current is typically 2.5 μA when there is no load and the supply voltage is 5.0 V.
    • This low quiescent current makes the device suitable for battery-powered applications.
  5. Thermal Shutdown (TSD):

    • The device will automatically shut down if the temperature exceeds 160°C to prevent thermal damage.
    • Ensure proper heat dissipation to avoid reaching this temperature.
  6. Operating Temperature (Topr):

    • The device operates reliably between -40°C and 85°C.
    • Avoid operating the device outside this temperature range to ensure stable performance.
  7. Storage Temperature (Tstg):

    • Store the device between -65°C and 150°C to prevent damage during storage.

Additional Notes:

  • Capacitors:
    • Use appropriate bypass capacitors (typically 10 μF) on the input and output to stabilize the supply and output voltages.
  • PCB Layout:
    • Ensure good thermal management by using a large copper area or heat sink if necessary.
  • Polarity:
    • Ensure correct polarity when connecting the device to avoid damage.
