LM2931AZ50R datasheet by STMicroelectronics

LM2931AZ50R Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2931AZ50R?
  The maximum input voltage that can be applied to the LM2931AZ50R is 26V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) of the capacitor should be less than 5 ohms.
• What is the maximum output current that the LM2931AZ50R can provide?
  The maximum output current that the LM2931AZ50R can provide is 500mA, but it's recommended to keep it below 400mA for reliable operation.
• How do I protect the LM2931AZ50R from overheating?
  To protect the LM2931AZ50R from overheating, ensure good thermal conductivity between the device and the PCB, and consider adding a heat sink if the device will be operating at high temperatures or with high input voltages.
• Can I use the LM2931AZ50R in a high-temperature environment?
  The LM2931AZ50R is rated for operation up to 125°C, but the output current should be derated at higher temperatures to prevent overheating.
