LTC1520CS#PBF datasheet by Linear Technology

LTC1520CS#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LTC1520CS?
  The maximum input voltage that can be applied to the LTC1520CS is 36V, although the recommended operating range is 4.5V to 36V.
• How do I ensure accurate voltage regulation with the LTC1520CS?
  To ensure accurate voltage regulation, make sure to decouple the input and output pins with suitable capacitors, and use a stable reference voltage source. Also, ensure that the output voltage is within the specified range and that the device is operated within the recommended temperature range.
• What is the purpose of the EN pin on the LTC1520CS?
  The EN (Enable) pin is used to turn the regulator on or off. When the EN pin is pulled high, the regulator is enabled, and when it is pulled low, the regulator is disabled and the output voltage is turned off.
• Can I use the LTC1520CS in a high-temperature environment?
  The LTC1520CS is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation. Consult the datasheet for specific derating guidelines.
• How do I calculate the output voltage of the LTC1520CS?
  The output voltage of the LTC1520CS is determined by the resistive divider network connected to the FB (Feedback) pin. The output voltage can be calculated using the formula: Vout = 1.25V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
