LM117K Frequently Asked Questions (FAQs)

  • The LM117K can handle input voltages up to 42V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 10uF, and keep the distance between the regulator and the capacitor as short as possible. Also, use a low-ESR capacitor to minimize oscillation.
  • The LM117K requires a minimum input voltage of 3.5V to regulate properly, but it's recommended to keep it above 4.5V for optimal performance.
  • The LM117K is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
  • Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit to protect the LM117K from input voltage surges and spikes. This will help prevent damage to the regulator and ensure reliable operation.
