L4973V5.1 datasheet by STMicroelectronics

L4973V5.1 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L4973V5.1?
  The maximum input voltage that can be applied to the L4973V5.1 is 40V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the L4973V5.1 is stable and doesn't oscillate?
  To ensure stability, make sure to use the recommended output capacitor value and type, and keep the input capacitor value below 10uF. Also, ensure the PCB layout is well-designed and follows good practices.
• What is the minimum input voltage required for the L4973V5.1 to operate?
  The minimum input voltage required for the L4973V5.1 to operate is 6.5V, but it's recommended to keep it above 7V for reliable operation.
• Can I use the L4973V5.1 in a high-temperature environment?
  The L4973V5.1 is rated for operation up to 150°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the L4973V5.1?
  The output voltage of the L4973V5.1 can be calculated using the formula: Vout = Vref x (1 + R2/R1), where Vref is the internal reference voltage (1.235V), and R1 and R2 are the feedback resistors.
