L4941BV Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L4941BV?
  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.
• How do I ensure the L4941BV is stable and doesn't oscillate?
  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.
• What is the minimum input voltage required for the L4941BV to operate?
  The minimum input voltage required for the L4941BV to operate is 7V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the L4941BV in a high-temperature environment?
  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.
• How do I calculate the output voltage of the L4941BV?
  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.
