LT1181CS datasheet by Linear Technology

LT1181CS Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT1181CS can handle?
  The LT1181CS can handle input voltages up to 80V, but it's recommended to limit the input voltage to 60V for reliable operation.
• How do I ensure the LT1181CS is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines, including the use of a 10uF output capacitor and a 1uF input capacitor. Also, ensure that the input and output capacitors are placed close to the IC.
• What is the minimum input voltage required for the LT1181CS to operate?
  The LT1181CS can operate with input voltages as low as 3.5V, but the output voltage regulation may not be guaranteed below 4.5V input.
• Can I use the LT1181CS in a high-temperature environment?
  The LT1181CS is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Ensure proper thermal management and heat sinking to prevent overheating.
• How do I calculate the output voltage of the LT1181CS?
  The output voltage of the LT1181CS can be calculated using the formula: Vout = (1 + R2/R1) * Vref, where R1 and R2 are the feedback resistors and Vref is the internal reference voltage (2.21V).
