Instructions for Use:

  1. Input Voltage (VIN):

    • Ensure the input voltage is within the range of 8V to 30V.
    • The higher the input voltage, the more power dissipation will occur, which may require additional heat sinking.
  2. Output Voltage (VOUT):

    • The output voltage is fixed at 12V. No external components are required to set this voltage.
  3. Output Current (IOUT):

    • The device can provide up to 1.5A of output current, with a typical value of 1A.
    • For continuous operation at higher currents, ensure proper heat dissipation.
  4. Quiescent Current (IQ):

    • The quiescent current is typically 5mA and can go up to 10mA.
    • This is the current consumed by the regulator when no load is applied.
  5. Dropout Voltage (VDROP):

    • The dropout voltage is the minimum difference between the input and output voltages required for the regulator to maintain regulation.
    • It is typically 1.3V and can go up to 1.7V.
  6. Line Regulation:

    • The line regulation is the change in output voltage due to changes in input voltage.
    • It is typically 0.01% and can go up to 0.05%.
  7. Load Regulation:

    • The load regulation is the change in output voltage due to changes in load current.
    • It is typically 0.01% and can go up to 0.05%.
  8. Thermal Shutdown (TSD):

    • The device will shut down if the junction temperature exceeds 160°C to prevent damage.
    • Ensure adequate cooling to avoid thermal shutdown.
  9. Operating Junction Temperature (TJ):

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

    • The storage temperature range is from -65°C to 150°C.
    • Store the device in a dry environment within this temperature range to maintain reliability.

Additional Notes:

  • Heat Sinking:
    • For high current applications, consider using a heat sink to improve thermal performance.
  • Capacitors:
    • Use input and output capacitors as recommended in the datasheet to stabilize the regulator and filter noise.
  • PCB Layout:
    • Follow good PCB layout practices to minimize noise and ensure stable operation.
