L4949EP Frequently Asked Questions (FAQ)

  • The L4949EP can handle input voltages up to 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 VIN and GND pins.

  • The L4949EP can operate with input voltages as low as 6.5V, but the output voltage regulation may not be guaranteed below 7V.

  • The L4949EP is rated for operation up to 150°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliable operation.

  • The output voltage of the L4949EP can be calculated using the formula: Vout = 1.25 x (1 + R2/R1), where R1 and R2 are the resistors used in the feedback network.
