L7985A Frequently Asked Questions (FAQs)

  • The L7985A can handle input voltages up to 35V, but it's recommended to keep it below 30V for reliable operation.
  • 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 regulator.
  • The L7985A is rated for operation up to 150°C, but its performance may degrade at high temperatures. Consider using a heat sink or a thermal pad to keep the junction temperature below 125°C.
  • Power dissipation (PD) can be calculated using the formula: PD = (Vin - Vout) x Iout. Make sure to consider the maximum power dissipation rating of 1.5W.
  • The L7985A has a dropout voltage of around 2V, making it suitable for low-dropout applications. However, the minimum input voltage should be at least 2V above the output voltage.
