LTC1153IS8 datasheet by Linear Technology

LTC1153IS8 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LTC1153IS8?
  The maximum input voltage that can be applied to the LTC1153IS8 is 36V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the LTC1153IS8 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10nF to 100nF capacitor between the VCC and GND pins to filter out noise.
• What is the minimum ESR (Equivalent Series Resistance) 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 LTC1153IS8 in a high-temperature environment?
  The LTC1153IS8 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.
• How do I calculate the output voltage ripple of the LTC1153IS8?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout x ESR) / (fsw x Cout), where Iout is the output current, ESR is the equivalent series resistance of the output capacitor, fsw is the switching frequency, and Cout is the output capacitance.
