LM34923MM/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM34923MM/NOPB is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure the stability of the output voltage, it's essential to use a minimum output capacitance of 10uF with an ESR of 1ohm or less, and to keep the output voltage within the recommended range of 0.8V to 15V.
  • The maximum output current that the LM34923MM/NOPB can deliver is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
  • To reduce the noise and ripple in the output voltage, it's recommended to use a low-ESR output capacitor, add a noise-reducing capacitor (e.g., 10nF) between the VOUT and GND pins, and to keep the input voltage as smooth as possible.
  • The thermal shutdown temperature of the LM34923MM/NOPB is typically around 150°C, but it can vary depending on the specific application and operating conditions.
