LT1058CN datasheet by Linear Technology

LT1058CN Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1058CN?
  The maximum input voltage that can be applied to the LT1058CN is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• How do I ensure the LT1058CN is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and add a 10nF-100nF capacitor between the VIN and GND pins to filter out noise.
• What is the minimum load current required for the LT1058CN to regulate properly?
  The LT1058CN can regulate properly with a minimum load current of 1mA, but it's recommended to have a load current of at least 10mA to ensure optimal performance and stability.
• Can I use the LT1058CN in a high-temperature environment?
  The LT1058CN 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 according to the temperature derating curve in the datasheet.
• How do I protect the LT1058CN from input voltage transients and surges?
  Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the LT1058CN from input voltage transients and surges. This will help prevent damage to the device and ensure reliable operation.
