Instructions for Using LT1460D1:

  1. Circuit Design:

    • Ensure the input voltage is within the specified range (2.7V to 36V).
    • Connect a bypass capacitor (typically 1μF) between the input and ground to filter out noise.
    • Place an output capacitor (typically 1μF) between the output and ground to stabilize the output voltage.
  2. Thermal Considerations:

    • The device can operate over a wide temperature range (-40°C to 125°C). However, ensure adequate heat dissipation if operating at high current or in high ambient temperatures.
  3. Output Voltage:

    • The LT1460D1 provides a fixed output voltage of 1.25V. If a different output voltage is required, consider using a different model or an adjustable version.
  4. Load Regulation:

    • The load regulation is very low (0.01%), ensuring that the output voltage remains stable even when the load current changes from 0 mA to 100 mA.
  5. Line Regulation:

    • The line regulation is also very low (0.01%), meaning the output voltage will remain stable over the full input voltage range.
  6. PSRR (Power Supply Rejection Ratio):

    • The device has a high PSRR of 70 dB at 1 kHz, which helps in rejecting noise from the input supply.
  7. Quiescent Current:

    • The quiescent current is 150 μA with no load, making it suitable for battery-powered applications where low power consumption is critical.
  8. Dropout Voltage:

    • The dropout voltage is 250 mV at 100 mA and 25°C, allowing the regulator to maintain regulation even when the input voltage is close to the output voltage.
  9. Storage Temperature:

    • Store the device in a temperature range of -65°C to 150°C to ensure its long-term reliability.
  10. Handling:

    • Handle the device with care to avoid damage from electrostatic discharge (ESD). Use proper ESD protection measures during handling and assembly.

By following these guidelines, you can ensure optimal performance and reliability of the LT1460D1 in your application.
