Part Number: TPS732 VBIAS电压虽然可以维持很高,但VIN一旦减小的很低就会使NMOS跨过饱和区进入可变电阻区。进入可变电阻区LDO也是在正常工作的吗?
Although the VBIAS voltage can be maintained very high, once the VIN is reduced very low, NMOS will cross the saturation region and enter the variable resistance region…
Part Number: TPS732 如果按照最小VIN=VOUT+VDO计算,VIN=1.2V(VFB)+0.15V(VDO最大值)=1.35V,而不是规格书中说的1.7V,这是为什么呢?
If the minimum VIN=VOUT+VDO is calculated, VIN=1.2V(VFB)+0.15V(maximum VDO)=1.35V, not 1.7V as stated in the specification, why is this?
