LTC1255CS8#PBF datasheet by Linear Technology

LTC1255CS8#PBF Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LTC1255CS8?
  The maximum power dissipation of the LTC1255CS8 is 1.4W, which is calculated based on the package thermal resistance and the maximum junction temperature.
• How do I ensure the stability of the LTC1255CS8 voltage regulator?
  To ensure stability, it is recommended to use a minimum output capacitance of 10uF, and to place the capacitor close to the output pin of the regulator. Additionally, the input capacitor should be at least 1uF to filter out noise and ripple.
• What is the minimum input voltage required for the LTC1255CS8?
  The minimum input voltage required for the LTC1255CS8 is 2.7V, which is the minimum voltage required for the internal voltage reference to operate correctly.
• Can I use the LTC1255CS8 in a high-temperature environment?
  The LTC1255CS8 is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. It is recommended to derate the power dissipation at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the LTC1255CS8?
  The output voltage of the LTC1255CS8 can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal voltage reference (2.5V), and R1 and R2 are the resistors used to set the output voltage.
