Instructions for Use:

  1. Input Voltage (VIN):

    • Ensure the input voltage is within the range of 4.5V to 5.5V to avoid damage to the device.
  2. Output Voltage (VOUT):

    • The output voltage is fixed at 3.3V. No external resistors are required for voltage adjustment.
  3. Output Current (IOUT):

    • The device can provide up to 250mA of output current, with a typical value of 200mA.
  4. Quiescent Current (IQ):

    • The quiescent current is typically 10μA and can go up to 20μA.
  5. Dropout Voltage (VDROP):

    • The dropout voltage is typically 0.3V and can be as high as 0.5V. Ensure the input voltage is sufficiently higher than the output voltage to maintain regulation.
  6. Load Regulation:

    • The load regulation is typically 0.5% and can vary up to 1%.
  7. Line Regulation:

    • The line regulation is typically 0.1% and can vary up to 0.5%.
  8. Power Dissipation (PD):

    • The maximum power dissipation is 1.25W. Ensure adequate heat sinking if operating near this limit.
  9. Operating Temperature (TOP):

    • The device operates reliably between -40°C and 85°C.
  10. Storage Temperature (TS):

    • Store the device between -65°C and 150°C to ensure long-term reliability.
  11. Mounting:

    • Solder the device according to the recommended footprint and ensure proper thermal management if high power dissipation is expected.
  12. Capacitors:

    • Use recommended input and output capacitors to stabilize the output and filter noise. Typically, 10μF ceramic capacitors are used for both input and output.
  13. Handling:

    • Handle the device with care to avoid static damage. Use appropriate ESD protection measures.
