Instructions for Use:

  1. Input Voltage (VIN):

    • Ensure the input voltage is within the range of 4.5V to 20V. Exceeding these limits can damage the device.
  2. Output Voltage (VOUT):

    • The output voltage is fixed at 3.3V. No external components are required to set this voltage.
  3. Output Current (IOUT):

    • The maximum continuous output current is 1.5A. Ensure that the load does not exceed this value to avoid overheating or damage.
  4. Quiescent Current (IQ):

    • The quiescent current is typically 5.0mA. This is the current drawn by the regulator when no load is applied.
  5. Dropout Voltage (VDROPOUT):

    • The dropout voltage is typically 1.2V. This is the minimum difference between the input and output voltages required for the regulator to maintain regulation.
  6. Load Regulation:

    • The load regulation is typically 2.0%, indicating the change in output voltage with varying load conditions.
  7. Line Regulation:

    • The line regulation is typically 0.1%, indicating the change in output voltage with varying input voltage.
  8. Ripple Rejection:

    • The ripple rejection is typically 60dB, which indicates the ability of the regulator to reject input ripple and noise.
  9. Operating Temperature (TOPR):

    • The operating temperature range is from -40°C to 125°C. Ensure the device operates within this range to avoid performance degradation or failure.
  10. Storage Temperature (TSTG):

    • The storage temperature range is from -65°C to 150°C. Store the device within this range to prevent damage.
  11. Package Type:

    • The S1117-33PI is available in a TO-252 package. Ensure proper handling and mounting to avoid mechanical stress.

Additional Notes:

  • Heat Dissipation: If the device is expected to operate near its maximum output current, ensure adequate heat sinking to manage thermal dissipation.
  • Capacitors: It is recommended to use input and output capacitors to stabilize the regulator and filter out noise. Typically, a 10μF ceramic capacitor on the input and a 10μF ceramic capacitor on the output are sufficient.
  • PCB Layout: Proper PCB layout is crucial for optimal performance. Keep the input and output traces short and wide to minimize inductance and resistance.
