Instructions for Use:

  1. Input Voltage (VIN):

    • Ensure the input voltage is within the range of 1.65V to 15V.
    • The input voltage should be at least 1.3V higher than the output voltage to maintain regulation.
  2. Output Voltage (VOUT):

    • The AMS1117-1.2V is designed to provide a stable 1.2V output.
    • No external components are required for this fixed output voltage version.
  3. Output Current (IOUT):

    • The maximum continuous output current is 1A.
    • Ensure the load does not exceed this limit to avoid overheating or damage.
  4. Thermal Considerations:

    • The device has a thermal shutdown feature that activates at approximately 160°C.
    • Use a heatsink if the device will operate near its maximum output current or in high ambient temperatures.
  5. Capacitors:

    • Place a 10μF tantalum or ceramic capacitor close to the input pin to ensure stability.
    • A 10μF tantalum or ceramic capacitor on the output pin is recommended to improve transient response and stability.
  6. PCB Layout:

    • Keep the PCB traces short and wide to minimize resistance and inductance.
    • Ensure proper grounding and decoupling to reduce noise and improve performance.
  7. Storage and Handling:

    • Store the device in a dry environment within the temperature range of -65°C to 150°C.
    • Handle with care to avoid static discharge and physical damage.
