LM1971M/NOPB Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the LM1971M/NOPB is -40°C to 125°C.
  • To ensure stability, it is recommended to use a minimum output capacitance of 10uF and an ESR of less than 1 ohm. Additionally, the input capacitor should be at least 1uF with an ESR of less than 1 ohm.
  • The maximum input voltage that the LM1971M/NOPB can handle is 26V. Exceeding this voltage may cause damage to the device.
  • The output voltage of the LM1971M/NOPB can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (1.25V), R1 is the resistance between the output and the adjust pin, and R2 is the resistance between the adjust pin and ground.
  • The quiescent current of the LM1971M/NOPB is typically around 5mA, but can be as high as 10mA under certain operating conditions.
