LM2940IMP-15/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM2940 is 26V, but it's recommended to keep it below 20V for reliable operation.
  • To ensure a stable 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.
  • The LM2940 is rated for operation up to 125°C, but its performance may degrade at high temperatures. Consider using a heat sink or a thermally-enhanced package if you expect high temperatures.
  • Use a transient voltage suppressor (TVS) or a voltage clamp diode in parallel with the input capacitor to protect the LM2940 from voltage spikes and transients.
  • Yes, the LM2940 is suitable for battery-powered devices due to its low quiescent current (IQ) of 3mA. However, consider using a low-dropout regulator (LDO) like the TLV703 for even lower IQ.
