LD2980ABM30TR datasheet by STMicroelectronics

LD2980ABM30TR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LD2980ABM30TR can handle?
  The maximum input voltage is 30V, but it's recommended to keep it below 28V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a 1uF capacitor on the EN pin to filter noise.
• What is the minimum input voltage required for the LD2980ABM30TR to operate?
  The minimum input voltage is 7V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the LD2980ABM30TR in a high-temperature environment?
  Yes, the LD2980ABM30TR can operate up to 125°C, but the output current may need to be derated above 85°C. Consult the datasheet for more information.
• How do I calculate the output voltage of the LD2980ABM30TR?
  The output voltage can be calculated using the formula: Vout = 1.23 x (1 + R2/R1), where R1 and R2 are the resistors connected to the FB pin.
