LTC1733EMSE#TR datasheet by Linear Technology

LTC1733EMSE#TR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LTC1733EMSE?
  The maximum input voltage that can be applied to the LTC1733EMSE is 18V, but it's recommended to keep it below 15V for reliable operation.
• How do I ensure the LTC1733EMSE 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 ceramic capacitor at the VCC pin, and a 1uF ceramic capacitor at the VIN pin. Also, keep the input and output capacitors close to the IC and use short traces.
• What is the minimum ESR required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.05Ω, but it's recommended to use a capacitor with an ESR of 0.01Ω or less for optimal performance.
• Can I use the LTC1733EMSE in a high-temperature environment?
  The LTC1733EMSE is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation. Consult the datasheet for more information.
• How do I calculate the output voltage of the LTC1733EMSE?
  The output voltage of the LTC1733EMSE can be calculated using the formula: VOUT = 1.25V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
