Hi Jutek
Power loss in an ldo is based on voltage drop across it and current through it, not by "on resistance" since the pass device is not used as a switch...why do you need to know "on resistance"..?
Thanks QQ

hello
what is the Ron resistance of PMOS pass device in the LDO? is that 1/gds?
regards
Do the math if you want to prove it. The term is Miller capacitance.

to calculate pole position properly.
one more question: Is input capacity of this PMOS equal to Cgs+Cgd?
