LM293D Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM293D is 26V, but it's recommended to keep it below 25V for reliable operation.
  • To ensure the output voltage is stable and within regulation, make sure to use a minimum of 10uF capacitor at the input and output pins, and keep the input voltage at least 2V above the desired output voltage.
  • The minimum input voltage required for the LM293D to regulate the output voltage is 7V for the 5V output version, and 10V for the 12V output version.
  • The LM293D is rated for operation up to 125°C, but the output current should be derated at higher temperatures to prevent overheating. Consult the datasheet for derating curves.
  • Use a TVS (transient voltage suppressor) diode or a voltage clamp at the input pin to protect the LM293D from input voltage transients and spikes.
