LT1181ACN datasheet by Linear Technology

LT1181ACN Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT1181ACN can handle?
  The LT1181ACN 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 LT1181ACN 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 VIN and GND pins to filter out noise.
• What is the minimum input voltage required for the LT1181ACN to operate?
  The minimum input voltage required for the LT1181ACN to operate is 7.5V, but it's recommended to use an input voltage of at least 10V for reliable startup and operation.
• Can I use the LT1181ACN in a high-temperature environment?
  The LT1181ACN is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliable operation. Consult the datasheet for thermal derating curves.
• How do I calculate the output voltage of the LT1181ACN?
  The output voltage of the LT1181ACN can be calculated using the formula: VOUT = (R1/R2) * (VIN - VREF), where R1 and R2 are the feedback resistors, VIN is the input voltage, and VREF is the internal reference voltage (2.21V).
