LM340AT-5.0 Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM340AT-5.0 is 35V, but it's recommended to keep it below 25V for reliable operation.
  • The LM340AT-5.0 is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures.
  • To ensure stability, use a minimum output capacitance of 10uF with an ESR of 5 ohms or less, and keep the input capacitance below 10uF.
  • No, the LM340AT-5.0 is a linear voltage regulator and not suitable for switching regulator applications. It's designed for low-dropout, low-noise, and high-PSRR applications.
  • The minimum input voltage required for the LM340AT-5.0 to regulate the output voltage is 7.5V, but it's recommended to keep it above 8V for reliable operation.
