L4949ED013TR datasheet by STMicroelectronics

L4949ED013TR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L4949ED013TR?
  The maximum input voltage that can be applied to the L4949ED013TR is 30V, but it's recommended to keep it below 28V for reliable operation.
• How do I ensure the L4949ED013TR 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 VIN and GND pins.
• What is the minimum input voltage required for the L4949ED013TR to operate?
  The minimum input voltage required for the L4949ED013TR to operate is 6.5V, but it's recommended to keep it above 7V for reliable operation.
• Can I use the L4949ED013TR in a high-temperature environment?
  The L4949ED013TR 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 L4949ED013TR?
  The output voltage of the L4949ED013TR 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 (1.235V).
