TLV3011-EP: decoupling capacitor value

Jan Bock
Expert 3135 points
Part Number: TLV3011-EP


Within the paragraph "board layout" , it is written that  1uF of decoupling capacitor is suggested. But on Figure 22 a capacitor of 10uF is shown.

Could you please inform me what should be the proper value of decoupling capacitors for TLV3011-EP? In the catalog version 10uF is suggested. 

 (left EP- Datasheet, right catalog part.)

 

Thanks 

Jan

    Hello Jan,

    The difference between 1uF and 10uF is little for this device. Any value 1uF and above is fine...whatever you have on hand.

    The 10nF is needed to provide the local charge for the fast edge rates of the output and should be as close to the supply pins as possible. The 1-10uF provides the general bulk bypassing.
