LT1170CQ datasheet by Linear Technology

LT1170CQ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1170CQ?
  The maximum input voltage that can be applied to the LT1170CQ is 15V, but it's recommended to keep it below 12V for reliable operation.
• How do I ensure stability in the LT1170CQ 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.
• What is the minimum load current required for the LT1170CQ to maintain regulation?
  The LT1170CQ can maintain regulation down to a minimum load current of 1mA, but it's recommended to have a minimum load of 10mA for optimal performance.
• Can I use the LT1170CQ in a high-temperature environment?
  The LT1170CQ 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 curves in the datasheet.
• How do I protect the LT1170CQ from input voltage transients?
  Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the LT1170CQ from input voltage transients. Also, make sure to follow proper PCB layout and grounding techniques to minimize noise and transients.
