LT1167ACS8 datasheet by Linear Technology

LT1167ACS8 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1167ACS8?
  The maximum input voltage that can be applied to the LT1167ACS8 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the internal circuitry.
• How do I ensure the LT1167ACS8 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and decoupling guidelines, use a low-ESR output capacitor, and avoid using long traces or wires that can introduce parasitic inductance.
• Can I use the LT1167ACS8 in a high-temperature environment?
  The LT1167ACS8 is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curve in the datasheet.
• How do I calculate the output voltage ripple of the LT1167ACS8?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where Iout is the output current, ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
• Can I use the LT1167ACS8 in a low-dropout (LDO) configuration?
  No, the LT1167ACS8 is not designed for LDO operation. It requires a minimum input-to-output voltage differential of 2.5V to maintain regulation. For LDO applications, consider using a dedicated LDO regulator like the LT1965.
