LT1513-2CR#PBF datasheet by Linear Technology

LT1513-2CR#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT1513-2CR can handle?
  The maximum input voltage that the LT1513-2CR can handle is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR capacitor for the output filter capacitor.
• What is the minimum input voltage required for the LT1513-2CR to operate?
  The minimum input voltage required for the LT1513-2CR to operate is 3.5V, but it's recommended to keep it above 4V for optimal performance.
• Can I use the LT1513-2CR in a high-temperature environment?
  The LT1513-2CR 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.
• How do I reduce the noise and ripple on the output voltage?
  To reduce the noise and ripple on the output voltage, use a low-ESR output capacitor, and add a noise-reducing capacitor (e.g. 10nF) between the output and ground. Also, keep the input and output capacitors close to the IC.
