LM293DGKR Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM293DGKR is 26V, but it's recommended to keep it below 24V for reliable operation.
  • The LM293DGKR 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.
  • The minimum input voltage required for regulation is 7.5V, but it's recommended to keep the input voltage at least 2V above the output voltage for reliable operation.
  • No, the LM293DGKR is a linear voltage regulator and is not suitable for switching regulator applications. It's designed for low-dropout linear regulation.
