LT1615ES5-1 datasheet by Linear Technology

LT1615ES5-1 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1615ES5-1?
  The maximum input voltage that can be applied to the LT1615ES5-1 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the device.
• How do I ensure the LT1615ES5-1 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a low-ESR output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the VIN and GND pins to filter out high-frequency noise.
• What is the minimum output current that the LT1615ES5-1 can deliver?
  The LT1615ES5-1 can deliver a minimum output current of 1mA, but it's recommended to use it with a minimum load of 10mA to ensure proper regulation and stability.
• Can I use the LT1615ES5-1 in a high-temperature environment?
  The LT1615ES5-1 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 calculate the output voltage of the LT1615ES5-1?
  The output voltage of the LT1615ES5-1 is set by the resistive divider network connected to the FB pin. Use the formula: VOUT = 1.25V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
