LT1381CS#TR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LT1381CS#TR?
  The maximum input voltage that can be applied to the LT1381CS#TR is 36V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the stability of the output voltage in the LT1381CS#TR?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the IC to minimize noise and oscillations.
• What is the maximum output current that the LT1381CS#TR can deliver?
  The maximum output current that the LT1381CS#TR can deliver is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
• How do I adjust the output voltage of the LT1381CS#TR?
  The output voltage of the LT1381CS#TR can be adjusted by using a resistive divider network between the output and the adjust pin. The output voltage is determined by the ratio of the resistors and the internal reference voltage.
• What is the purpose of the adjust pin in the LT1381CS#TR?
  The adjust pin is used to adjust the output voltage of the LT1381CS#TR. It can also be used to implement a soft-start function by connecting a capacitor to the adjust pin and a resistor to the output.
