LT1172CN8 datasheet by Linear Technology

LT1172CN8 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1172CN8?
  The maximum input voltage that can be applied to the LT1172CN8 is 15V, but it's recommended to keep it below 12V for reliable operation.
• How do I ensure stability in the LT1172CN8 voltage regulator?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the regulator to minimize parasitic inductance.
• Can I use the LT1172CN8 in a high-temperature environment?
  The LT1172CN8 is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to derate the output current and voltage according to the temperature derating curve in the datasheet.
• How do I calculate the power dissipation of the LT1172CN8?
  The power dissipation of the LT1172CN8 can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
• Is the LT1172CN8 short-circuit protected?
  Yes, the LT1172CN8 has built-in short-circuit protection, which limits the output current to a safe value in case of a short circuit. However, it's still recommended to add external protection, such as a fuse or a current-limiting resistor, to prevent damage to the regulator and surrounding components.
