LM140LAH-12 Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM140LAH-12 is 35V, but it's recommended to keep it below 25V for reliable operation.
  • To ensure a stable and accurate output voltage, make sure to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a minimum capacitance of 10uF. Also, keep the input voltage ripple low and use a good quality input capacitor.
  • The minimum input voltage required for the LM140LAH-12 to function properly is 14.5V, but it's recommended to keep it above 15V for reliable operation.
  • The LM140LAH-12 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
  • To protect the LM140LAH-12 from input voltage surges and spikes, use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input to limit the voltage to a safe level.
