hi,thanks for all of you
1.if my LDO can supply 0~8mA current, and the load regulation is 7mV;but I only use 8mA ,so should I care the load regulation of 7mV
2.what is the maxium current which the LDO supply?I think it is related with the lowest supply voltage.
using TSMC .18um process,can I use 3.3V voltage ?eg.nmos:vds,vgs,vgd,vgb,vdb those voltage can be 3.6V?my nmos length can be large than 0.18um(for example 1u or 0.35um)
thanks all
there is one nmos2v mosfet i want to use it in 3.6V,can it breakdown?what's the breakdown condition?i find someone think the vgs is the important parameter.but I think the condition of all parameter vgs ,vdg,vgb,vdb.
thank all~
hi~all
if my LNA need 4mA(dc),I'm designing the LDO which supply the crrent to LNA,so how much current does the LDO need to supply?(I think is about 6mA)
hi,all
In LDO ,there is one mos which provide current to load.I'm adoubting that need I confirm that the state of mos is always in saturation?
when load current is very low ,it's must not in "saturation region"
thanks all ~

I have a digital power management named DVDDA,so I have some quesion to ask for help:
1.Imin~Imax:HOW to define the Imax(is it the max current which comes out in transient?I need to simulate the max current of my Digital current when I power on my vdd)
AS in the fig,1,(2,3,4)?which is my max...
that is to say:what standard to justify the min-max current.for example:in VDD transit simulation,the maxim current is 30mA which is appear at start .so the max current is 30mA?
thanks all of you
in my system.it just a transient 0mA current load.it happens when my LDO is working ,then after several us my load current can increase a value.it just a very short time.must I consider this condition?
