L4941BV Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the L4941BV is 30V, but it's recommended to keep it below 28V for reliable operation.
  • To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor, and add a 10nF capacitor between the Vref and GND pins.
  • The minimum input voltage required for the L4941BV to operate is 7V, but it's recommended to keep it above 8V for reliable operation.
  • The L4941BV is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
  • The output voltage of the L4941BV can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.5V), and R1 and R2 are the resistors in the output voltage divider.
