LT1431CZ datasheet by Linear Technology

LT1431CZ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1431CZ?
  The maximum input voltage that can be applied to the LT1431CZ is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the device.
• How do I ensure the LT1431CZ is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a low-ESR output capacitor, and add a 10nF-100nF capacitor between the VCC and GND pins to filter out noise.
• What is the minimum output current that the LT1431CZ can supply?
  The minimum output current that the LT1431CZ can supply is 1mA, but it's recommended to keep the output current above 10mA to ensure optimal performance and regulation.
• Can I use the LT1431CZ in a high-temperature environment?
  The LT1431CZ is rated for operation up to 125°C, but it's recommended to derate the output current and voltage as temperature increases to prevent overheating and ensure reliability.
• How do I calculate the output voltage of the LT1431CZ?
  The output voltage of the LT1431CZ can be calculated using the formula: VOUT = (R1/R2) * (1.25V), where R1 and R2 are the resistors connected to the VOUT and ADJ pins, respectively.
