LM293DR Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM293DR is 26V, but it's recommended to keep it below 24V for reliable operation.

  • Yes, the LM293DR can be used as a voltage regulator for a microcontroller, but it's essential to ensure the output voltage and current meet the microcontroller's requirements.

  • The output voltage of the LM293DR can be calculated using the formula: Vout = (R1 / R2) * (Vin - Vref), where R1 and R2 are the resistors used to set the output voltage, Vin is the input voltage, and Vref is the reference voltage (typically 2.5V).

  • The minimum input voltage required for the LM293DR to operate is 7V, but it's recommended to keep it above 8V for reliable operation.

  • The LM293DR is rated for operation up to 125°C, but it's essential to ensure proper heat sinking and thermal management to prevent overheating.
