LM34914SD/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM34914SD/NOPB is 18V. Exceeding this voltage may damage the device.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the output voltage can be stabilized by adding a 10nF capacitor between the VOUT and GND pins.
  • The maximum output current that the LM34914SD/NOPB can deliver is 2A. Exceeding this current may cause the device to overheat or shut down.
  • The output voltage of the LM34914SD/NOPB can be configured by connecting a resistor divider network between the VOUT and GND pins. The output voltage can be calculated using the formula: VOUT = 1.25V x (R1 + R2) / R2.
  • The thermal shutdown temperature of the LM34914SD/NOPB is 150°C. If the device temperature exceeds this value, it will shut down to prevent damage.
