LM34936-Q1: What is 10 Ohm resistor propose at Vin's PIN

Part Number: LM34936-Q1

Hi Ti staff,

I found the 10 Ohm resistor connect series at Vin PIN of this ICs. I can not find the reference for what the propose of this resistor.

1- Could you tell me why this resistor is connected in your reference schematic (SNVSB97 page 20), how do you select the values?

2- Is this resistor the same propose of Boot resistor to reduce the noise?

  • Hello Narukom,

    1. The 10 ohm resistor and the 100nF capacitor are an RC filter. These values should normally be good and do not need to be changed.

    2. This RC filter reduces noise on the VIN pin.

    Best regards,
    Brigitte
