TMP1075: Power supply ripple requirement

Muyan Lin
Prodigy 50 points
Part Number: TMP1075


Supply power ripple requirement are not mentioned in the datasheet. 3V power supply ripple at 210mV, does it affect chip application?

    Hello Muyan,

    We do not specify the maximum ripple voltage.  Section 8.5 does show the temperature accuracy vs. supply voltage.  You also want to be aware of the power supply thresholds for Power-on reset(1.22V) and Brown-out(1.1) reset.   

    Section 11 of the datasheet also provides power supply recommendations.  Please note that the typical bypass capacitor is 0.01uF, but you may require something larger to clean up noise.
