LM293ST Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM293ST is 26V, but it's recommended to keep it below 24V for reliable operation.

  • To ensure a stable output voltage, make sure to use a suitable output capacitor with a minimum value of 10uF, and keep the input voltage within the recommended range. Also, ensure the device is properly decoupled from the input voltage source.

  • The minimum input voltage required for the LM293ST to function properly is 7V, but it's recommended to keep it above 8V for reliable operation.

  • The LM293ST 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 LM293ST 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 within the recommended range.
