L4949EP-E Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the L4949EP-E is 28V, but it's recommended to keep it below 24V 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 VIN and GND pins.
  • The minimum input voltage required for the L4949EP-E to operate is 6.5V, but it's recommended to keep it above 7V for reliable operation.
  • The L4949EP-E 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 L4949EP-E can be calculated using the formula: Vout = (R1 / R2) * (VIN - Vref), where R1 and R2 are the resistors in the feedback network, VIN is the input voltage, and Vref is the internal reference voltage (2.5V).
