[FAQ] LMR70503: Minimum Input/Output Capacitance

Part Number: LMR70503

Hello,

The datasheet isn't too clear on the required minimum input and output capacitance.    Specifically I'm concerned about DC bias with ceramic capacitors.

Does TI have a calculator, or other recommended method for determining the minimum value in this case?

  • Hello Don,

    The minimum input capacitor is given with 10uF and the minimum output capacitor with 22uF. Please make sure that DC bias does not cause more than 50% derating.

    Best regards,
    Brigitte
