LT1087CT datasheet by Linear Technology

LT1087CT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1087CT?
  The maximum input voltage that can be applied to the LT1087CT is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent internal voltage regulator overheating.
• How do I ensure stability and prevent oscillations in the LT1087CT?
  To ensure stability and prevent oscillations, make sure to use a minimum output capacitance of 10uF, keep the output capacitor ESR below 1 ohm, and avoid using ceramic capacitors with high ESL (Equivalent Series Inductance).
• What is the minimum load current required for the LT1087CT to maintain regulation?
  The LT1087CT can maintain regulation with 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 LT1087CT in a high-temperature environment?
  The LT1087CT 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 at high temperatures to ensure reliable operation.
• How do I protect the LT1087CT from input voltage transients and surges?
  Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input to protect the LT1087CT from voltage transients and surges. Also, ensure that the input capacitor is rated for the maximum input voltage and has a low ESR.
