KA317MRTM Frequently Asked Questions (FAQ)

  • The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help reduce input ripple and improve stability.

  • To ensure stability, use a minimum output capacitor of 22uF, and ensure the output capacitor's ESR (Equivalent Series Resistance) is less than 5 ohms. Additionally, keep the input and output capacitors close to the IC, and use a ground plane to reduce noise and inductance.

  • The maximum input voltage for the KA317MRTM is 40V, but it's recommended to keep the input voltage below 35V to ensure reliable operation and prevent damage to the IC.

  • The KA317MRTM is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to prevent overheating and ensure reliable operation.

  • The output voltage of the KA317MRTM can be calculated using the formula: Vout = Vref x (1 + R2/R1), where Vref is the internal reference voltage (1.25V), R1 and R2 are the resistors in the voltage divider network.
