Instructions for Use:

  1. Input Voltage (VIN):

    • Ensure the input voltage is within the specified range of 4.5V to 36V.
    • Do not exceed the maximum input voltage to avoid damage.
  2. Output Voltage (VOUT):

    • The device provides a regulated output voltage of 5.0V.
    • Verify the output voltage using a multimeter before connecting sensitive components.
  3. Output Current (IOUT):

    • The maximum continuous output current is 2.0A, with a typical value of 1.5A.
    • Ensure that the load does not exceed these limits to prevent overheating or damage.
  4. Quiescent Current (IQ):

    • The quiescent current is typically 10μA and can go up to 20μA.
    • This is the current consumed by the regulator when there is no load.
  5. Dropout Voltage (VDO):

    • The dropout voltage is typically 0.8V at a load current of 1.5A.
    • Ensure that the input voltage is at least 0.8V higher than the output voltage to maintain regulation.
  6. Load Regulation:

    • The load regulation is typically 0.5%, indicating the change in output voltage for changes in load current.
    • This ensures stable output voltage under varying load conditions.
  7. Line Regulation:

    • The line regulation is typically 0.1%, indicating the change in output voltage for changes in input voltage.
    • This ensures stable output voltage under varying input conditions.
  8. Ripple Rejection:

    • The device has a ripple rejection of 70dB, which helps in filtering out input voltage ripple.
    • Use appropriate capacitors on the input and output to further reduce ripple.
  9. Operating Temperature (TJ):

    • The junction temperature should be kept within the range of -40°C to 125°C.
    • Use proper heat sinking if operating at high currents or in high-temperature environments.
  10. Storage Temperature (TS):

    • The device can be stored in temperatures ranging from -65°C to 150°C.
    • Ensure that the device is not exposed to extreme temperatures for extended periods.

Additional Notes:

  • Capacitors:
    • Use ceramic capacitors with low ESR for input and output filtering.
    • Typical values are 10μF for the input and 10μF for the output.
  • PCB Layout:
    • Place the input and output capacitors as close as possible to the regulator pins.
    • Use wide traces for power connections to minimize voltage drop.
  • Heat Dissipation:
    • For high-current applications, ensure adequate heat dissipation.
    • Consider using a heatsink if the device will be operating near its maximum current capacity.
