LT1513-2IR#PBF datasheet by Linear Technology

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

• What is the maximum input voltage that can be applied to the LT1513-2IR#PBF?
  The maximum input voltage that can be applied to the LT1513-2IR#PBF is 18V, but it's recommended to keep it below 15V for reliable operation.
• Can I use the LT1513-2IR#PBF in a high-temperature environment?
  The LT1513-2IR#PBF 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 reliable operation.
• How do I ensure the stability of the LT1513-2IR#PBF output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, avoid using ceramic capacitors with high ESL values.
• Can I use the LT1513-2IR#PBF in a low-dropout application?
  The LT1513-2IR#PBF has a dropout voltage of around 1.5V, so it's not suitable for low-dropout applications. Consider using a low-dropout regulator like the LT1965 instead.
• How do I calculate the power dissipation of the LT1513-2IR#PBF?
  The power dissipation of the LT1513-2IR#PBF can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Iq is the quiescent current.
