Instructions for Use:

  1. Input Voltage (VIN):

    • Ensure the input voltage is within the range of 2.5V to 40V.
    • The input voltage should be at least 0.5V higher than the desired output voltage to maintain regulation.
  2. Output Voltage (VOUT):

    • The output voltage can be adjusted using external resistors.
    • For fixed output voltages, use the appropriate resistor values as specified in the datasheet.
  3. Quiescent Current (IQ):

    • The quiescent current is typically 80 μA when the output voltage is 5V and no load is present.
    • This low quiescent current helps in extending battery life in portable applications.
  4. Dropout Voltage (VDROPOUT):

    • The dropout voltage is typically 0.5V at an output current of 100mA.
    • Ensure that the input voltage remains above the sum of the output voltage and the dropout voltage to maintain regulation.
  5. Load Regulation:

    • The load regulation is typically 0.01% over the load range from 0 to 100mA.
    • This indicates minimal change in output voltage with varying load conditions.
  6. Line Regulation:

    • The line regulation is typically 0.01% over the input voltage range from 5V to 40V.
    • This ensures stable output voltage even with variations in input voltage.
  7. PSRR (Power Supply Rejection Ratio):

    • The PSRR is typically 75dB at 1kHz.
    • This high PSRR helps in filtering out noise from the power supply.
  8. Operating Temperature Range (TJ):

    • The device is designed to operate over a temperature range from -40°C to 125°C.
    • Ensure that the ambient temperature and heat dissipation are managed to keep the junction temperature within this range.
  9. Storage Temperature Range (TSTG):

    • The device can be stored at temperatures ranging from -65°C to 150°C.
    • Avoid exposing the device to extreme temperatures for extended periods.
  10. Transient Response:

    • The transient response is not specified but is generally fast enough to handle typical load changes.
    • For critical applications, consider adding external capacitors to improve transient response.
  11. PCB Layout:

    • Place the input and output capacitors close to the device to minimize parasitic inductance.
    • Use a ground plane to help dissipate heat and reduce noise.
  12. Package Information:

    • The LT1114S#PBF is available in a surface-mount package.
    • Follow the recommended PCB layout and soldering guidelines provided in the datasheet to ensure reliable operation.
