LT1072CN8 datasheet by Linear Technology

LT1072CN8 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1072CN8?
  The maximum input voltage that can be applied to the LT1072CN8 is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
• How do I ensure stability in the LT1072CN8 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 and use a low-ESR capacitor for the output.
• What is the minimum load current required for the LT1072CN8 to maintain regulation?
  The LT1072CN8 can maintain regulation down to a minimum load current of 10mA, but it's recommended to have a minimum load current of 100mA for optimal performance.
• Can I use the LT1072CN8 in a high-temperature environment?
  The LT1072CN8 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability. Consult the datasheet for thermal derating curves.
• How do I protect the LT1072CN8 from input voltage transients?
  Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the LT1072CN8 from input voltage transients. Also, consider adding a series resistor to limit the input current during transients.
