LT1170CT datasheet by Linear Technology

LT1170CT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1170CT?
  The maximum input voltage that can be applied to the LT1170CT is 15V, but it's recommended to keep it below 12V for reliable operation.
• How do I ensure stability in the LT1170CT 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 LT1170CT in a high-temperature environment?
  The LT1170CT 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 LT1170CT?
  The power dissipation of the LT1170CT can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current.
• Can I use the LT1170CT in a switching regulator application?
  No, the LT1170CT is a linear voltage regulator and is not suitable for switching regulator applications. It's designed for low-dropout, low-noise, and high-PSRR applications.
