Instructions for Using AMS1117S OT223 AMS1117-3.3:

  1. Input Voltage:

    • Ensure the input voltage is within the range of 3.0V to 15.0V.
    • Higher input voltages can cause overheating and damage the regulator.
  2. Output Voltage:

    • The output voltage is fixed at 3.3V.
    • Use appropriate capacitors on the input and output to stabilize the voltage and reduce ripple.
  3. Output Current:

    • The maximum continuous output current is 1.0A.
    • For higher currents, consider using a heatsink or a more powerful regulator.
  4. Dropout Voltage:

    • The dropout voltage is approximately 1.3V at full load.
    • Ensure the input voltage is at least 1.3V higher than the output voltage to maintain regulation.
  5. Quiescent Current:

    • The quiescent current is typically 5.0mA.
    • This is the current consumed by the regulator when it is active but not supplying any load.
  6. Shutdown Current:

    • The shutdown current is very low, around 0.001A.
    • Use the enable pin to turn the regulator on and off as needed.
  7. Operating Temperature:

    • The operating temperature range is from -40°C to 125°C.
    • Ensure adequate cooling if operating in high-temperature environments.
  8. Storage Temperature:

    • The storage temperature range is from -65°C to 150°C.
    • Store the regulator in a dry and cool place to prevent damage.
  9. Capacitor Recommendations:

    • Use a 10μF tantalum or ceramic capacitor on the input side.
    • Use a 10μF tantalum or ceramic capacitor on the output side to ensure stability.
  10. PCB Layout:

    • Place the input and output capacitors as close as possible to the regulator.
    • Ensure good thermal management with a heatsink if necessary.
  11. Enable Pin:

    • If the enable pin is used, connect it to a logic high level to activate the regulator.
    • Connect it to ground to shut down the regulator.
  12. Safety Precautions:

    • Always use appropriate fuses and protection circuits to prevent damage from overvoltage or short circuits.
    • Handle the regulator with care to avoid static discharge which can damage the component.
