LM123K/883C Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM123K/883C is 40V, but it's recommended to keep it below 35V for reliable operation.

  • To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 5 ohms. Additionally, add a 1uF to 10uF ceramic capacitor in parallel with the output capacitor to improve stability.

  • The minimum input voltage required for the LM123K/883C to regulate the output voltage is typically 2V above the output voltage (e.g., 7V for a 5V output). However, this can vary depending on the specific application and load conditions.

  • The LM123K/883C is rated for operation up to 125°C (257°F), but its performance may degrade at high temperatures. Ensure proper heat sinking and derate the output current accordingly to prevent overheating.

  • Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input to protect the LM123K/883C from voltage transients and spikes. This is especially important in automotive or industrial applications where voltage surges are common.
