LM293H/NOPB Frequently Asked Questions (FAQs)

  • The LM293H can operate from -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C.
  • While the LM293H can handle up to 1A of output current, it's not recommended for high-current applications due to thermal limitations. Consider using a heat sink or a more suitable regulator for high-current applications.
  • To ensure stable and accurate output voltage, make sure to use a suitable output capacitor (e.g., 10uF) and a minimum load current of 5mA. Also, keep the input voltage within the recommended range and avoid noise and ripple on the input.
  • No, the LM293H is not designed as a dropout regulator. It has a minimum dropout voltage of around 2V, which means the input voltage must be at least 2V higher than the output voltage. For dropout regulator applications, consider using a different device.
  • To protect the LM293H from input voltage transients and surges, consider adding a transient voltage suppressor (TVS) or a voltage clamp diode at the input. Also, ensure the input capacitor is rated for the maximum input voltage.
