    Part Number: TPS74901 Hi team, As we know that the VBias must be 1.75V above Vout. In this case, Vbias need at least > 3.35V(1.8V+1.75V = 3.35V). but the board doesn't have 5V source. Could we use resisters to divide 12V source to 5V for VBias? If…

    Hi Dhanabal, TPS7A57 has a current source reference and an internal unity-gain LDO buffer, this allows to set Vout using the REF with a single resistor, compared to more traditional LDOs that use a voltage reference. The DAC53204RTER has a Current-Output…

    Part Number: TPS74901 Other Parts Discussed in Thread: TPS740 Hi, I am using the TPS74091 to generate 1.8V from 2.5V. Can I connect Vbias to the same 2.5V as Vin? Or it has to be 1.75V larger than 1.8V? Thank you.
